'Grace of God' in the Bible

I thank my God always on your behalf, for the grace of God which is given you by Jesus Christ;

But we did not receive the spirit of the world, but the Spirit which is from God, that we might know the things that have been given to us by the grace of God;

According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon.

But by the grace of God I am what I am: and his grace which was bestowed upon me was not in vain; but I laboured more abundantly than they all: yet not I, but the grace of God which was with me.
