The book of John is all about believing. Believing that Jesus is Messiah, God’s son come to Earth as a man to redeem a people for himself.
A people that would love, follow and obey Him, a people who would deeply desire a relationship with the God who made them, a people that understood their flaws and fallen-ness but who also understood God’s mercy and grace.
In the book of John we find twelve disciples who believed deeply in Jesus (John 2:11) so much so that they left everything to follow Jesus. We see Nicodemus a ruler of the Jews who discovers what it means to be born again (John 3). John tells us of a used and abused Samaritan woman who found the “living water” of Jesus and true forgiveness. It is she who lead the whole village of Sycar to believe in Jesus (John 4).
We see a Gentile official believing in Jesus after Jesus healed his son (John 4). Many believed in Jesus as he healed, fed and ministered to the crowds (John 6-7). Let us not forget about the man who was born blind. Jesus not only heals his physical blindness but he heals his spiritual blindness as well. Jesus performed many miracles but by far the greatest miracle was when he raised Lazarus from the dead.
He did it powerfully and publically. No other miracle produced more believers that this one miracle.
His words had power
