'Dominion' in the Bible

For if while we were enemies we were reconciled to God through the death of His Son, it is much more certain, having been reconciled, that we will be saved [from the consequences of sin] by His life [that is, we will be saved because Christ lives today].

For sin will no longer be a master over you, since you are not under Law [as slaves], but under [unmerited] grace [as recipients of God’s favor and mercy].
