Yet God, in His grace, freely makes us right in His sight. He did this through Christ Jesus when He freed us from the penalty for our sins.
Romans 3:24 (NLT)
The only way man can be justified and made right with God is by the blood of the Lord Jesus Christ. So if our sins have been forgiven and redeemed from sin, it is because Christ Jesus paid the full price.
We have been justified and made right with God by grace and not by our own good works. There is nothing good we can do to erase the sin that separated us from God. There is no price we could afford to redeem our lives from the death penalty. But God provided us with a way. To be saved, we must believe in Jesus Christ, the son of the living God. Salvation can never be obtained as a reward, payment or by any other measure of man's worth. It is grace alone, the undeserved kindness of God that redeems us and makes us righteous.
All we can do is accept His free gift by believing on His name and give Him all the praise and glory that He alone deserves.
May God bless you all!
