John 4:4 (GNT)
Jesus had zeal. John 14:12 says, "Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father." Let your prayer be that you have the same zeal that Jesus had.
The 3rd and final point is Jesus went to an unreached area. He needed to go through Samaria, because it was very dangerous. God didn't let anything happen to him. When you through tough neighborhoods to do His work, or even in your city and town, remember that God, Grace, Mercy, and The Holy Ghost go with you.
I believe in you and you need to believe in yourself.
