Very good post.
True submission is when we place ourselves under the mighty hand of God, and allow Him to deal with the root of our sin, which is an inclination towards unbelief, pride, and self idolatry, and progressively transform us to be inciined to faithfulness, humility, and God worship
It is a process of sanctification that begins but does not end at the new birth, although justification and positional sanctification are a completed work, this work is not completed until we are like Him when we see Him just as He is. At the second advent
This process is just as much a part of grace as justification and positional sanctification
