SUFFICENT

2 Corinthians 12:9-10 (KJV)
“9 And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.
10 Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong.”
The emphasis here is not our weakness it is His strength. Grace transforms; it is when grace changes us we are redeemed, regenerated, and justified. It is a work of faith not fate.
Our transformation is deliberate and executed by faith; got to want it, see it, believe it, and receive it. Some things we cannot change; nonetheless, if we have the mind to do so, we can change. Positioning our mind and spirit for change positions His strength in us.
Therefore, grace does not justify our sins; it works His presence so deep in us "we" become justified, and His presence becomes the work He is working in us. Justification begins the moment we surrender to His love and the strength it gives. His strength is the focus, He is our focus; God is all sufficient. God can and God will when His will become our will; in this His grace is always enough.
God is basically telling Paul no matter how much you come to know and encounter in revelation you will always need me. We are never strong enough that we do not need Him, therefore, our weakness becomes basis for relationship; needing God gives purpose to salvation and God’s desire for Paul was to keep it that way.
