Verse 6 Even as David also describeth; that is, David in a similar manner describeth.--Unto whom God imputeth righteousness without works; whom God justifies and saves, though he has not performed his duty. The force of the passage quoted from David in the Psalms 32:1,2; Romans 4:7,8, in respect to its application to the apostle's argument, appears to be this,--that it represents spiritual blessedness as consisting in the pardon of sin, and not in the reward of goodness; and this sustains the position that Paul has been aiming to establish, viz., that human salvation is, in all cases, dependent on grace,--that is, on undeserved favor,--and not on merit.
