I disagree (Isaiah 50)
John 10:27-30 disagrees with you. To be saved means to assent to His Lordship. You are no longer your own. Hew bought you out of the market with His Blood, and not even you yourself can escape His ownership. And He never lets go. If you do not understand this, know this, and agree with it, you are not saved. Romans 3:22-26.
