“For Jehovah is loyal in his love,
And he has great power to redeem.
He will redeem Israel from all their errors.”
~Psalm 130:7,8

“Redeem” connotes a number of things:
You can redeem a coupon, in which case the literal meaning is to exchange.
You can redeem something you pawned, in which case you are recuperating something valuable.
You can redeem a mortgage, which basically means you’ve paid off a great debt.
You can also redeem abstract things, like when you fulfill a promise.
You can redeem people, including yourself, when you or someone else recovers your reputation.
It is possible for God to redeem us from sin because He has exchanged the perfect life of his son for each person born into sin (Rom. 5:8).
He has paid off our debt and recuperated our chance to live forever.
Because of Christ’s sacrifice, Jehovah can fulfill his promise to save those who exercise faith in His son (John 3:16).
His pardon is so great that He can even reestablish our reputation (Isa. 1:18).
How can we make use of God’s loyal love?
We must show appreciation for what He does for us (Mic. 6:8).
