FREELY given to us of God
Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are FREELY given to us of God.
1Cr 2:13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
1Cr 2:14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know [them], because they are spiritually discerned.
1Cr 2:15 But he that is spiritual judgeth all things, yet he himself is judged of NO MAN.
That is one of the outstanding results on embracing Grace, "what do we have that was not FREELY given to us.
This takes away the ground for all boasting (hence, separating from one another as we judge someone not worthy of our fellowship). Only Jesus gets the glory!
Must guard against becoming proud of our revelation of Grace! Always giving others grace as we have received it so freely! "Freely you have received, freely give" Jesus!
