'Effect' in the Bible

And I went up by revelation; and I put before them the good news which I was preaching among the Gentiles, but privately before those who were of good name, so that the work which I was or had been doing might not be without effect.

I do not make the grace of God of no effect: because if righteousness is through the law, then Christ was put to death for nothing.

Now this I say: The law, which came four hundred and thirty years after, does not put an end to the agreement made before by God, so as to make the undertaking without effect.
