Do I Frustrate My Grace?

If it is a religion of works, then Christ death was in vain, or without success.  But it wasn’t in vain, for we that believe, believe unto righteousness. So in order to be pleasing to God, you must believe what he said about you. You must work with your faith; or with your belief, so that he can reach out to you and raise you up. Let no man condemn you in the law of carnal ordinances. But approach the throne of God on the basis of the blood of his Son.

Gal. 2:20,21

20 I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. 21 I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.

Hebrews 11:6

6. But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
