V.1-4 To go from Judea (in the South) to Galilee (in the North) a person would have to pass through Samaria.
V.5-42 Although the Lord Jesus is not wanted in Judea, He is happy to spend time in winning a sinful woman. He is the Giver of living water. Try all she could, her heart could not be satisfied. But it was only when her conscience was touched that she realized she was speaking to no ordinary man.
V.28-42 She showed the sure sign of a believer, she immediately wanted to tell others about the Lord Jesus. If you have never told anyone about the Lord Jesus being your Savior, then you are not sure you are saved (Rom. 10:9-10).
V.43-54 But He had other work to do. He could raise from the dead if necessary. Now he cures this son who was at the point of death — a picture of Israel as a nation. After the Lord Jesus comes for the believers, He is going to raise up Israel from their present condition of being as dead.
