Romans 4:21-24 And being fully persuaded that, what he had promised, he was able also to perform. And therefore it was imputed to him for righteousness. Now it was not written for his sake alone, that it was imputed to him; But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead
‘Fully persuaded that, what he had promised, he was able also to perform’ his soul was full of confidence that the Word of God bound Him to fulfil what He had promised. After 25 years, it was fulfilled. Faith was imputed for righteousness (4:3-22; Heb. 11:8-12).
‘And therefore it was imputed to him for righteousness.’ Imputation: justification from all sin. [Hebrew: chashab] to be reckoned or put to the account of one; charge with. Equivalent to the Greek word logizomai, translated numbered (Mark 15:28); accounted (Rom. 8:36; 1Cor. 4:1; Gal. 3:6; Heb. 11:19); counted (Rom. 2:26; 4:3, 5; 9:8; Php. 3:13); laid to their charge (2Tim. 4:16); reckoned (Luke 22:37; Rom. 4:4,9,10; 6:11; 8:18); and impute (Rom. 4:6, 8, 11, 22-24; 2Cor. 5:19; Jas. 2:23).
Imputation is that act of God in salvation whereby He accounts the believer righteous in Christ because Christ bore his sins and because he has properly repented of his sins and met God’s terms of reconciliation (Rom. 3:24-31; 4:1-25; 2 Cor. 5:14-21; Gal. 3:6-9, 13-14).
‘It was not written for his sake alone’ Genesis 15:6 was written for all mankind.
‘If we believe on him that raised up Jesus our Lord from the dead’ the condition of the gospel is faith, not only temporary faith, but steadfast and continued faith. We can have joyful faith in, and acceptance of Christ as the substitute for sin and our Saviour whereby one receives salvation (Mark 16:16; Acts 4:12; 10:43; Rom. 1:16; 3:24-31; Ephes. 2:8-9); access into grace (Rom. 5:2); fulfilment of the promises (Heb. 6:12); the Holy Spirit (Gal. 3:14); righteousness (Rom. 4; 9:30, 32; 10:6; Php. 3:9); sonship (Gal. 3:26); healing (Jas. 5:14-16; 1Pet. 2:24); eternal life (John 3:15-18, 36; 5:24; 6:47); and answers to every prayer (Mat. 7:7-11; 21:21; Mark 11:22-24; Luke 18:1-8; John 14:12-15; 15:7, 16).
