A paradox is "a statement that seems contradictory, unbelievable, or absurd but that may actually be true in fact." Jesus told Pilate that His kingdom was not of this world (John 18:36). The kingdom of God does not follow the rules or restrictions of this physical world. Because of this, the Bible contains many paradoxical statements regarding the nature of the kingdom of God.

We are made free by becoming bondservants (Romans 6:17-18).

We become strong by becoming weak (2 Corinthians 12:10).
We live by dying (John 12:24-25; 2 Corinthians 4:10-11).
