Contemporary English Version (CEV)
C.S. Lewis talked about how there can be only two true reactions to Jesus Christ -- he is either certifiably crazy or he is Lord of the universe, but he cannot be anything else. He is not simply another good teacher or a nice man who wanted to help people. He made claims to be the Son of God, the Messiah, the Savior of the world, and the religious leaders recognized the threat that he was and put him to death for such claims.
We cannot react indifferently to Jesus. His claim to be first in our hearts must be met with either resistance or with submission, but to simply let him dwell among other, lessor gods is to reject his claims. To follow him is to seek to put him first, to reject the false gods that try to claim our loyalty. It is an active thing, submitting to Christ daily, and each morning should start with an effort to serve him in all things that day.
The crowds in his day marveled at what he taught. May we marvel as well, doing so in awe because we know that the man who claimed to be Lord is the same man who predicted his own death and resurrection. That man, I will follow anywhere.
