'Promise of God' in the Bible

What, then, though some of them did not believe? Shall their unbelief make the promise of God without effect?

(What the Law produces is the Wrath, not the promise of God; where there is no law, there is no transgression either.)

He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;

Is the law, then, against the promise of God? God forbid. Howbeit, if there had been a law given which could have given life: then no doubt righteousness should have come by the law.

By faith Joseph, when he was dying, referred to [the promise of God for] the exodus of the sons of Israel [from Egypt], and gave instructions concerning [the burial of] his bones [in the land of the promise].

but we look for 'new heavens and a new earth,' where righteousness shall have its home, in fulfillment of the promise of God.
