'Inheriting' in the Bible

Therefore, [inheriting] the promise depends entirely on faith [that is, confident trust in the unseen God], in order that it may be given as an act of grace [His unmerited favor and mercy], so that the promise will be [legally] guaranteed to all the descendants [of Abraham]—not only for those [Jewish believers] who keep the Law, but also for those [Gentile believers] who share the faith of Abraham, who is the [spiritual] father of us all—

so that you will not be [spiritually] sluggish, but [will instead be] imitators of those who through faith [lean on God with absolute trust and confidence in Him and in His power] and by patient endurance [even when suffering] are [now] inheriting the promises.
