'Aside' in the Bible

I do not ignore or nullify the [gracious gift of the] grace of God [His amazing, unmerited favor], for if righteousness comes through [observing] the Law, then Christ died needlessly. [His suffering and death would have had no purpose whatsoever.]”

Brothers and sisters, I speak in terms of human relations: even though a last will and testament is just a human covenant, yet when it has been signed and made legally binding, no one sets it aside or adds to it [modifying it in some way].

Do not be deceived, God is not mocked [He will not allow Himself to be ridiculed, nor treated with contempt nor allow His precepts to be scornfully set aside]; for whatever a man sows, this and this only is what he will reap.
