For all the promises of God find their Yes in him. That is why it is through him that we utter our Amen to God for his glory.
(2 Corinthians 1:20 ESV)
By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was in the act of offering up his only son, of whom it was said, “Through Isaac shall your offspring be named.” He considered that God was able even to raise him from the dead, from which, figuratively speaking, he did receive him back. (Hebrews 11:17-19 ESV)
… by which he has granted to us his precious and very great promises, so that through them you may become partakers of the divine nature, having escaped from the corruption that is in the world because of sinful desire.
(2 Peter 1:4 ESV)
Since we have these promises, beloved, let us cleanse ourselves from every defilement of body and spirit, bringing holiness to completion in the fear of God. (2 Corinthians 7:1 ESV)
“Every time a godly man reads the Scriptures … and there meets with a promise, he ought to lay his hand upon it and say, ‘This is part of my inheritance, it is mine, and I am to live upon it.’” ~ Jeremiah Burroughs
“Faith provides a firm standing-ground while I await the fulfillment of God’s promises. Faith furnishes my heart with a sure support during the interval. Faith believes God and relies upon His veracity: as it does so, the heart is anchored and remains steady, no matter how fierce the storm nor how protracted the season of waiting….Real faith issues in a confident and standing expectation of future things.” ~ A. W. Pink
“…God’s promises lift our aspirations higher. On our own we would be content with some happy relationships; God wants us to have union with the Son of God. We aspire for earthly success; he intends for us heavenly glory. We would settle for health and wealth; yet he has everlasting life in store for us.
Such was the case with Abram. He wanted a son, but God intended that he would become the father of all the redeemed. Already God had told Abram that through him he would bless all the nations (Gen. 12:3). But Abram’s appetite was shaped, as ours generally is, by his local and recent experience—by his felt needs, as they call it today. He just wanted the caravan leaders to think highly of him. He wanted to know the human joy of looking into the eyes of a son. He wanted respect; he wanted to fit in; he wanted to feel good. These are things we want, too. They are good things, as far as they go, but they fall short of what God intends for us. Paul reminds us, ‘No eye has seen, nor ear heard, nor the heart of man imagined, what God has prepared for those who love him’ (1 Cor. 2:9). To keep us from filling ourselves on lesser things, God leaves us in circumstances of want and also gives us promises of great blessing, far beyond our imagining.” ~ Richard Phillips
