John 4, speaks about the first real evangelist spreading the good news of Christ the Messiah. It is the woman at the well, a Samaritan, scorned and rejected by her many ex husbands, yet used by God to tell the good news.
Genesis 6 . Sin and wickedness got worse and worse on earth. God saw it and decided to start over. But Noah, his wife, his three sons and their wives, eight in all found favor with God, so God told him to build an ark. This Noah did, and it was the biggest ship built until the time of Ptolemy (around 215 BC.)
Ponder that the first evangelist was a scorned woman who happened to meet Jesus, and that Noah, being obedient to God built the ark on dry land, too big to be of any use unless there was going to be a giant flood. This takes faith!
