John Calvin Commentary Romans 4:24

"but for our sake also, unto whom it shall be reckoned, who believe on him that raised Jesus our Lord from the dead," — Romans 4:24 (ASV)

Who believe on him, etc. I have already reminded you of the design of those periphrastic expressions: Paul introduced them so that he might, according to what the passages may require, describe in various ways the real character of faith — of which the resurrection of Christ is not the smallest part, for it is the ground of our hope regarding eternal life. If he had only said that we believe in God, it could not have been so readily learned how this could serve to obtain righteousness; but when Christ comes forth and presents to us in his own resurrection a sure pledge of life, it then appears evident from what source the imputation of righteousness flows.
