Non-believers or atheists often deny the supremacy of Jesus. This is not surprising to anyone.
Many of the Jews and people of Jesus’ time did not believe in him, either. The Jews expected a powerful general.
We as a culture also look up to strength, power and influence. Jesus appeared as a poor and lowly servant, which is not what the world now or then looks up to.
To most of us, being a lowly servant seems “foolish” compared to today’s culture.
