“Being justified freely by his grace through the redemption that is in Christ Jesus:”
King James Version (KJV)
3:24 And are justified - Pardoned and accepted. Freely - Without any merit of their own. By his grace - Not their own righteousness or works. Through the redemption - The price Christ has paid. Freely by his grace - One of these expressions might have served to convey the apostle's meaning; but he doubles his assertion, in order to give us the fullest conviction of the truth, and to impress us with a sense of its peculiar importance. It is not possible to find words that should more absolutely exclude all consideration of our own works and obedience, or more emphatically ascribe the whole of our justification to free, unmerited goodness.
Ro 3:24 Being justified freely by his grace. All who believe upon Jesus Christ have their sins thus blotted out, being freely, as a divine gift, justified (that is, counted just, or sinless) by grace, through the redemption that is in Christ Jesus. Christ redeems the sinner who puts his trust in him. His blood pays the debt that the sinner owes to justice. Since Christ, the sinless One, has suffered for sin, God will accept his suffering for the debt of those who love and trust in him.
