I disagree. There is no choosing. Jesus was clear. We must trust and obey Him. So it is not about what we choose to do, we do it. We are either slaves to flesh and sin or slaves to His Grace. We call Him Lord for a reason and that means we submit ourselves to His Will and not the flesh/sin.
I hear you, and accept that that is your position.
I just believe that submitting to his will means submitting to Matthew 22:37-40 and John 13:34 as the supreme interpreter of all Law, because that is what I believe He commanded us to do in those very commandments.
So we disagree, but we have shared out beliefs with each other in peace. We could have done worse.
May Jesus continue to guide us both.
