Paul says...
But by the grace of God I am what I am, and his grace to me was not without effect. No, I worked harder than all of them--yet not I, but the grace of God that was with me.
1 Corinthians 15:10
God's grace works through the Christian! This is has nothing to do with us!
Its by the grace of God that a Christian receives revlation of His Word.
Its by the grace of God that a Christian can pray for hours on end
Its by the grace of God that a Christian can fast, preach, prophecy, worship, evangelize etc.
God gives different graces to His people so that He can be glorified!
He is the one that makes the person great or small. Our job is just to be faithful in whatever He has given to us!
Isn't that great news?!
It means that I can stop trying to be perfect and understand that its not about me but what God is doing through me. Even when I screw up I glorify God! (not that it gives us an excuse to sin)
After realizing this grace. I can finally stop trying to do things so that I can be "good enought to preach/teach" but I can just DO IT IN FAITH because its God working through me.
It sorta kills the pride that I had but it is also a relief!
I can stop worrying about every word I say and action I make to "look good" and just be!
