If justification is freely given by grace, what made it possible for God to extend such favor without compromising His justice? This verse points to a crucial act that secured our freedom.
The final part of the verse explains how this free gift of grace is applied: 'through the redemption that is in Christ Jesus.' Redemption, in its core meaning, is the act of buying back or setting free by paying a price. In this context, it refers to the saving work of Jesus Christ.
Christ's life, death, and resurrection serve as the ultimate 'ransom' or 'price' that liberated humanity from the bondage of sin and its penalty. It’s through His sacrifice that God’s justice is satisfied, allowing Him to justly declare us righteous. This redemption isn't something we achieve; it's something accomplished in Christ and by Christ. He is the one who paid the cost, making it possible for God's grace to flow to us as a justified people.
