1. If anyone is thirsty (37-39)
On the last day of the feast Jesus stood and gave an invitation to all thirsty people to come to him (See Isaiah 55:1.). He promised to give streams of living water that would flow from within. John explained that this was a promise of the Holy Spirit who would be poured out on all believers after sin had been defeated by Jesus' death and resurrection. The Spirit is given not only to bless the believer; he comes to make the believer a blessing to others.
2. No one ever spoke like this man (40-52)
There was a division of opinion about Jesus. Some received his words and knew that he was the promised Messiah. Others, basing their opinion on inadequate information, rejected him. (They did not know that Jesus was indeed born in Bethlehem.) The temple guards angered the Pharisees by their testimony (46, 47). Nicodemus asked for a fair hearing, and was squelched.
Application: Lord, give me the streams of living water flowing out to bless others.
One Word: Jesus, streams of living water
