Reading the books of Moses, we learn after 400 years in Egypt the Israelite had grown accustomed to their Egyptian lifestyle which made them rebel against God’s plan for them to go and take the promised land he promised to give them, but refused when they were told by their spies of its giant inhabitants.
Numbers 14: 2 All the Israelites grumbled against Moses and Aaron, and the whole assembly said to them, "If only we had died in Egypt! Or in this desert!
3 Why is the Lord bringing us to this land only to let us fall by the sword? Our
wives and children will be taken as plunder. Wouldn't it be better for us to
go back to Egypt?" 4 And they said to each other, "We should choose a leader and go back to Egypt."
The Israelites did not believe in God’s promise that he would go before them and help them defeat their enemies in the promised land. They just feared what the spies said that there were giants in that land that would destroy them. They did not believe God and treated Him with contempt and wanted a new leader to take them back to Egypt and this angered God.
Numbers 14: 11 The Lord said to Moses, "How long will these people treat me with contempt? How long will they refuse to believe in me, in spite of all the miraculous signs I have performed among them?
The Israelites had witnessed all the wonders of God’s miraculous signs against the Egyptians, walked through the parted Red Sea and watched their enemy being covered by the sea and destroyed, receiving daily bread from heaven. Witnessing all these miracles by God and yet they did not believe His promise to give them this promised land. Their contempt angered God and he would not allow them to enter his promise land.
Numbers 14:21 Nevertheless, as surely as I live and as surely as the glory of the Lord fills the whole earth, 22 not one of the men who saw my glory and the miraculous signs I performed in Egypt and in the desert but who disobeyed me and tested me ten times- 23 not one of them will ever see the land I promised on oath to their forefathers. No one who has treated me with contempt will ever see it.
The spies that gave the bad report were killed by God which made the Israelites fear God realizing they have sinned and then presumed that God still wanted them to go and take the promised land which God commanded he would not let them enter.
Numbers 14: 40 Early the next morning they went up toward the high hill country. "We have sinned," they said. "We will go up to the place the Lord promised."
41 But Moses said, "Why are you disobeying the Lord 's command? This will not succeed! 42 Do not go up, because the Lord is not with you. You will be defeated by your enemies, 43 for the Amalekites and Canaanites will face you there. Because you have turned away from the Lord, he will not be with you and you will fall by the sword." 44 Nevertheless, in their presumption they went up toward the high hill country, though neither Moses nor the ark of the Lord 's covenant moved from the camp. 45 Then the Amalekites and Canaanites who lived in that hill country came down and attacked them and beat them down all the way to Hormah.

It is dangerous to assume the will of God and not know his will from what he commands and teaches from Scripture. Presuming God’s will lead to destruction like these presumptive Israelites.
Never assume what God’s will is, you need to always know it is God’s word. When you hear someone says something about God’s will you are responsible to know it is from Scripture and not assume. Knowing God’s word is the firm foundation to know what is true to God.
God is faithful in keeping his promises and he did not tolerate any contempt by the Israelites who did not obey his commandments. Abraham believed God’s promise to give his offspring’s this promised land, but the Israelites had no faith in God and wanted to return to Egypt. They feared the giants more than believing God’s promise that he would go before them and fight for them.
Israelites often treated God with contempt, and he wanted to wipe them out, but Moses would appeal to him to forgive them and God relented and forgive them but still punished those who showed him contempt.
In the NT we find a God of grace through his Son to forgive sin and not condemn. Jesus was the promised Messiah that the Jews were waiting for, but Jesus was not the Messiah the Jews assumed he would be and refused to accept Jesus as their Messiah. Instead they held fast to the laws of Moses.
Mark 2: 5 When Jesus saw their faith, he said to the paralytic, "Son, your sins are
forgiven." 6 Now some teachers of the law were sitting there, thinking to themselves, 7 "Why does this fellow talk like that? He's blaspheming! Who can forgive sins but God alone?" 8 Immediately Jesus knew in his spirit that this was what they were thinking in their hearts, and he said to them, "Why are you thinking these things? 9 Which is easier: to say to the paralytic, 'Your sins are forgiven,' or to say, 'Get up, take your mat and walk'? 10 But that you may know that the Son of Man has authority on earth to forgive sins . . . ." He said to the paralytic, 11"I tell you, get up, take your mat and go home."
The teachers of the law did not accept Jesus’ authority to forgive sin because they did not believe he was their Messiah. They showed contempt towards Jesus, but Jesus showed his authority to forgive sin by healing the paralytic to prove he was sent by God which Isaiah said the Messiah would set the oppressed free.
Jesus did not condemn them for their contempt for him but forgave them. Jesus forgave even to the point where he was dying on the cross asking his Father to forgive them for not knowing what they were doing.
The Jewish leaders were unwilling to repent because they assumed the Messiah would follow the laws of the Old Testament. They refused to become a new creation in Christ which Jesus said they need to do in his parable.
Mark 2: 20 But the time will come when the bridegroom will be taken from them, and on that day they will fast. 21 "No one sews a patch of unshrunk cloth on an old garment. If he does, the new piece will pull away from the old, making the tear worse. 22 And no one pours new wine into old wineskins. If he does, the wine will burst the skins, and both the wine and the wineskins will be ruined. No, he pours new wine into new wineskins."

Jesus teaches to understand his teachings you cannot remain in your old OT beliefs or assumptions you must become a new creation in Christ.

2 Corinthians 5: 17 Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come!

Being a new creation is to always remain new in your understanding of Christ as you continually study God’s words. Receiving Jesus’ teachings as living and growing in you through the Holy Spirit who will help you mature and transform your mind to grown in having the whole knowledge Christ.
This transformation of God’s OT law to his law of grace and forgiveness through faith in his Son is found in these passages.
In the OT, God commanded if anyone did any work on the Sabbath they must be die.
Numbers 15: 32 While the Israelites were in the desert, a man was found gathering wood on the Sabbath day. 33 Those who found him gathering wood
brought him to Moses and Aaron and the whole assembly, 34 and they kept him in custody, because it was not clear what should be done to him. 35 Then the Lord said to Moses, "The man must die. The whole assembly must stone him outside the camp." 36 So the assembly took him outside the camp and stoned him to death, as the Lord commanded Moses.

To break the Sabbath law meant death. Jesus changes this Sabbath law to his.

Mark 2:23 One Sabbath Jesus was going through the grainfields, and as his disciples walked along, they began to pick some heads of grain. 24 The Pharisees said to him, "Look, why are they doing what is unlawful on the
Sabbath?"
The Pharisee saw God’s Sabbath law in Numbers 15 being broken. This being the Lord’s law only the Lord could change that law, which Jesus did.

Mark 2: 25 He answered, "Have you never read what David did when he and his
companions were hungry and in need? 26 In the days of Abiathar the high priest,
he entered the house of God and ate the consecrated bread, which is lawful only for priests to eat. And he also gave some to his companions." 27 Then he said to them, "The Sabbath was made for man, not man for the Sabbath. 28 So the Son of Man is Lord even of the Sabbath."

Jesus reminds the Pharisees that David also broke God’s law because he was God’s anointed and now God’s anointed Son is with them and he is Lord over the Sabbath and has the authority to change the Sabbath law.
Jesus said the Sabbath law was made for man to rest from his work and not a law not to work because of a Sabbath day. Jesus proclaims that he is the Lord of the Sabbath and now we rest in Him and not in the law. Jesus has become our eternal Sabbath rest in God.

Hebrews 4 explains this Sabbath rest we have in Jesus.

Hebrews 4: 1 Therefore, since the promise of entering his rest still stands, let us be careful that none of you be found to have fallen short of it. 2 For we also have had the gospel preached to us, just as they did; but the message they heard was of no value to them, because those who heard did not combine it with faith. 3 Now we who have believed enter that rest, just as God has said, "So I declared on oath in my anger, 'They shall never enter my rest.' " 4 And yet his work has been finished since the creation of the world. For somewhere he has spoken about the seventh day in these words: "And on the seventh day God rested from all his work." 5 And again in the passage above he says, "They shall never enter my rest." 6 It still remains that some will enter that rest, and those who formerly had the gospel preached to them did not go in, because of their disobedience.
7 Therefore God again set a certain day, calling it Today, when a long time later
he spoke through David, as was said before: "Today, if you hear his voice, do not harden your hearts." 8 For if Joshua had given them rest, God would not have spoken later about another day. 9 There remains, then, a Sabbath-rest for
the people of God; 10 for anyone who enters God's rest also rests from his own work, just as God did from his. 11 Let us, therefore, make every effort to enter that rest, so that no one will fall by following their example of disobedience.
Jesus is our sabbath rest through faith in him who gives us an eternal rest with God in heaven. We no longer depend on the laws made for the Sabbath which the Israelites did not believe would give them rest. That is why the sabbath was just a shadow of the eternal rest we would have in Jesus.
Colossians 2: 16 Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day.
17 These are a shadow of the things that were to come; the reality, however, is
found in Christ.
This reality in Christ only comes to those whose wine skin remains new and have become a new creation in Christ where the old has gone and new has come.
Your sabbath rest is in the name of Jesus, the Son of God, our Lord and Savior.
