Wow, a hot thread. Hate arriving late on the scene
By the way, the "first works" are not my own, they are His work.
I can't make myself right with God, He's made me right with God. Our nature wants to give us a key role in this grand story, robbing the grandeur and amazingness of His Grace. It's too bad... We are able to confess with our mouth and believe in our heart (turning our hearts toward Jesus = repenting).
Belief is not lip service (though it could be just as easy as tongues-babbling). Believing is the most primal form of Christ's disciple-making. It's only possible through/by the Spirit. It's heart-level, life-changing, born-again producing, etc..
