We can rely on God in all circumstances despite the temptation and deceptions of Satan that would have us think otherwise. It is only our belief and trust in Jesus that will give us eternal life because of His sacrifice on the cross when He took the punishment for our sins.

Being a follower of Jesus is something that is freely offered to people but comes at a great cost, you must be willing to give up everything. Are you willing to do that?

At the start of Chapter 20, Jesus has been exercising the disciple's faith, in that He has risen from the grave. Now He wants them to believe that He truly is the Messiah, the Son of God. He does this by coming to them and reassuring them that He is alive and then commissions them to tell the world about the forgiveness that was accomplished by His death on the cross and proven by His resurrection from the grave.

What does it mean to be a disciple of Jesus? It means that you follow Him, it means that you trust Him, it means that you turn back to Him when you have gone astray. Peter experienced all of this as the rooster crowed on that fateful night.

Jesus knows that His time is running out and His disciples are going to be facing a lot of grief in the coming days, so He prepares and encourages them now. Here in this passage, He reminds them that if they are found in Him they will have peace, no matter what this life may bring.
