I once thought that evangelism is sharing the gospel to unbelievers outside of church. Like Billy Graham who had big tent gathering to reach unbelievers outside of church.
I also assumed that everyone who goes to church knows the gospel and wanted eternal life with God.
The Lord has allowed me to witness in myself and in others in church that we did not truly know and understands the gospel of Jesus that saves to bring us home to our Father in heaven. I also learned that I truly do not know who will go to heaven. Only God knows the heart and mind of what people believe is true to him and be saved.
Jesus calls us to go make disciples for him meaning we are responsible to teach new believers the gospel of Jesus that will save them.
In Ephesians 4, one of the gifts in the church is the evangelists and they also were gifted to prepare the church for works of service to build it up so that they all reach unity in their faith in the complete knowledge of Jesus.
So, evangelism is to be taught in the church.
Jesus said that his gospel is a narrow path and door to his Father and only a few find it.
So, we should not assume that everyone in church is the few that are on Jesus’ narrow path to his Father if they are not being evangelized to know and understand the whole gospel truth.
Eternal life comes through knowing what is having faith in Jesus as your Lord and Savior and being obedient to his teachings and commandments because you love him. This is what should be evangelized in church to keep everyone on the narrow path to be with God forever because no one comes to the Father but through the Son and no one comes to the Son unless his Father calls them to him.

We must evangelize that God’s promise of eternal life is not because you do good works in church or that you follow God’s laws. Eternal life is promised through God’s grace and faith in Jesus. That is why we must evangelize in church so that no one falls short of being in God’s rest, eternal life which Hebrews warns.

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 it did not combine it with faith. 3 Now we who have believed enter that rest,

The Israelites fell short of receiving God’s promise rest in the promise land because when the gospel was preached to them, they did not value it and had no faith in it. It is the same for us today that we must preach clearly the whole gospel message of Jesus so that no one fall short and off the narrow path of God’s promise of eternal rest with him.

Pastors are not the only one responsible for church members falling short of their salvation. Pastors are responsible to preach the gospel, but they are not responsible for members to know and understand the gospel and have faith in it. We are brothers and sisters in Christ, so this responsibility falls upon every family member in church.

Everyone who has confessed Jesus as their Lord should have faith and understanding of how not to fall short in their love for God and should recognize when someone is falling short or do not love for Jesus because the do not obey his teachings and commandment or really want eternal life.

They come to church just to make friends and for the social activities. There will some who will do things to win hearts for themselves, some seek to have important status or authority in church. They all are looking out for their own interest and not what interest Christ. We who are mature in Christ are called to correct and admonish them with the gospel to save them so that they will repent and be saved.

There will be those who come seeking God because they were once lonely and felt unloved but found the God who loves them and now are seeking to know and love him. We who love Jesus are responsible to evangelize to them and teach them the gospel so that can be one with God and his family and not fall short of their salvation.

The clear sign of our salvation is when we long to be with Jesus.

Hebrews 9:28 so Christ was sacrificed once to take away the sins of many
people; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him.

When your hope is in being with Jesus it becomes the anchor of your salvation because this hope keeps you on his narrow path home to our Father.

Be safe in Jesus, Ps. Glenn.
