3 Then Abram said, “Look, You have given me no offspring; indeed one born in my house is my heir!” 4 And behold, the word of the Lord came to him, saying, “This one shall not be your heir, but one who will come from your own body shall be your heir.” 5 Then He brought him outside and said, “Look now toward heaven, and count the stars if you are able to number them.” And He said to him, “So shall your descendants be.” 6 And he believed in the Lord, and He accounted it to him for righteousness” (Genesis 15:3–6, NKJV).
God accounted Abraham’s faith to him for righteousness (v. 6). All who have the faith of Abraham are his seed and heirs (Rom. 4:16; Gal. 3:8-9, 29). The nature of Abraham’s faith has long been disputed. Was his faith “faith only?” No, for James said Abraham’s works (obedience) completed his faith (James 2:21-24). His obedient faith was accounted for righteousness, as is ours. Such faith does not earn or merit the blessing, for we are sinners saved by grace (Rom. 3:23-24; 4:1-5). The apostle Paul used Genesis 15:6 in Romans 4:22, where its context gives us valuable insight into the nature of Abraham’s faith (Rom. 4:18-22). Abraham believed “in hope,” trusting God’s promise of a son, even though he and Sarah were past the age of having children. Instead of doubting God’s word, Abraham “did not waver” but was “strengthened in faith,” assured God would fulfill His word. And He did. “Sarah conceived and bore Abraham a son in his old age” (Gen. 21:2). Abraham’s unwavering, active, obedient faith was accounted for righteousness. Like Abraham, our trusting, obedient faith will be accounted to us for righteousness.
