The grace of God was never intended to be abused, or used as a weapon (Rom. 6:1). As a weapon of vanity, a saint would call on 'Jesus' name with the desire that He would fight for them (2 Cor. 6:1-18).
These saints never consider changing their own thoughts or behaviors (Rom, 12:1). Thoughts create behaviors. Behaviors create experiences. Experiences write our testimony (Rev 12:11; 1 Co 1:6; 2 tim 1:8; 1 Co 15:10).
