The last thing most of us want to be is submissive. We think of a choke hold or tapping out. We don't like to be dominated.
Submitting to Jesus comes from a completely different perspective. Jesus does not have us in a choke-hold, forcing us to comply. Instead, he is offering us a better way to live, and we willfully submit to his leadership. Choosing his ways over our own, because he knows more about His creation that we do.
