“My grace is sufficient for you…”-{2 Corinthians 12:9}
Grace here speaks of His empowering , and note it is present tense “is,” and it is His grace that moment by moment is “enough” as the word “sufficient” here speaks of, with the implication it “satisfies!”
As oxygen is to the body so is grace to the soul.

His grace supplies Salvation-{Eph 2;8-9}; Standing with God,{Rom 5:2};Strengthens,-{2 Tim 2:1};For Service -{2 Cor 9:8};Sanctifies{changes us}-{Titus 2:11-13};Sustains, Satisfies.-{2 Cor 12;9}. It is Sufficient for this moment and when you arrive at the next moment it will be available and sufficient for that moment too and the moments beyond that for you.

Paul was given this promise when God had said “No” to his plea to have his “thorn” removed from him.In his pain, for the word “thorn” was used of a tent peg used to impale someone with! In his pain the Lord gave him,Himself and a promise, and in this Paul gloried, boasted of His provision for him! “That is why, for Christ’s sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.”-{2 Cor 12:10}

Celebrate and thank the God of ALL Grace, whose grace is gifted to you not merely to survive but thrive!

“And God is able to make ALL GRACE abound to you, so that always having all sufficiency in everything, you may have an abundance for every good deed;.”-( 2 Cor 9:8)
