'Effect' in the Bible

For what? if some have not believed, shall their unbelief make the faith of God of none effect?

For if they which are of law be heirs, faith is made vain, and the promise made of no effect.

begging of us with much entreaty to give effect to the grace and fellowship of the service which was to be rendered to the saints.

Now I say this, A covenant confirmed beforehand by God, the law, which took place four hundred and thirty years after, does not annul, so as to make the promise of no effect.
