 That line is a close echo of what Jesus says in the Gospel of John, especially Jesus in John 15:21.

In that passage, he is speaking to his disciples about coming opposition. The full idea is essentially:

People will mistreat or reject his followers “because of my name,” and the reason is that they do not truly know the One who sent him.

The “one who sent me” refers to God the Father in Christian theology. The point of the passage isn’t just about ignorance in an intellectual sense, but a deeper spiritual rejection—if people don’t recognise or accept Jesus’ message, they also don’t understand (or accept) the God he represents.

So the verse is mainly about:

• Expectation of persecution for his followers
• The idea that rejecting Jesus is tied to not knowing God
• Framing opposition as rooted in misunderstanding or disbelief rather than informed choice

If you want, I can  show the exact surrounding passage or  explain how different Christian traditions interpret it.
