Read This: John 3:1-3
A non-sequitur is a statement that doesn’t logically follow from the previous statement.
Nicodemus wouldn’t have come to Jesus if he wasn’t looking for something. He was trying to understand who Jesus was. God must have sent him because he’s doing things only God can do.
Acts of God were nothing new. The Scriptures were full of them, from His creation of the universe to His calling of Abraham, delivering His people from Egypt, guiding and providing for them in the wilderness, protecting them from their enemies — and all the miracles done through Moses and the prophets. The Jewish people knew the power and presence of God.
Now here was this Jesus, saying and doing things that reminded Nicodemus of stories he’d read in Scripture. Stories about prophets seeing and hearing things they were not privy to, causing jars of oil to not run out, multiplying food to feed groups of people, and facing kings down with righteous indignation.
God, the Creator of everything, was known to supernaturally intervene when His people needed provision, protection, or confrontation. And He usually did it through men. Such men served God’s interests and communicated His will. And God had promised to send another such man in the future. A Messiah, who would restore the kingdom to Israel. God’s kingdom. God’s king.
When you read Jesus’ answer to Nicodemus’s question, it seems a non-sequitur. Actually, it was exactly what Nicodemus was looking for — but could not yet see.
