John the Baptist Prepares the Way
The 'word of God' came to John and told him about a way to repent for forgiveness of sins through baptism. John spread the word all around Jordan. There was a prophecy from Isaiah that this would happen. Crowds came out to get baptized by him and he insulted them calling them a brood of vipers. He tells them to bear fruit to go along with their repentance or like a tree not bearing fruit, they will be cut down and thrown in the fire.
The crowd asks him what they can do, he gives a few examples but basically says to help each other out, when you have excess give some to people who have nothing. Also don't extort money from people. The people thought that he was great and were thinking that he might be the Christ. He said that he was simply baptizing with water but someone is coming that is much better than me, who will baptize you with the holy spirit and with fire.
John did a bunch more preaching including some criticism of Herod, which will be among the reasons he winds up in jail later. Everyone gets baptized, including Jesus, and the heavens open up and the holy spirit descended in a dove-like form and says Jesus is the son of God.
A little more detail on John the Baptist, that is nice I guess. I thought it was interesting that when he was telling people to be generous he specifically told tax collectors not to take extra money and soldier not to extort people. I also found it interesting that when Jesus was baptized the "heavens were opened". What does that mean? I read that in biblical times they believed that above us was a dome that held the clouds and stars and such, and heaven was up there. I wish a had a reference, I can't remember where I read that.

I'll be honest, I didn't really read this, scanning the page it looks like it is just a bunch of "...son of _____ who was son of ____" and I just don't care.
