“For what does the Scripture say? “Abraham believed God, and it was accounted to him for righteousness.” Now to him who works, the wages are not counted as grace but as debt. But to him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness, just as David also describes the blessedness of the man to whom God imputes righteousness apart from works: “Blessed are those whose lawless deeds are forgiven, And whose sins are covered; Blessed is the man to whom the Lord shall not impute sin.”” Romans 4:3-8 (NKJV)
Abraham:
Even Abraham, who lived before the time of Law given by Moses or Grace came through Jesus Christ, God called him righteous just because Abraham believed in God. This is the grace of our God and the Lord Jesus Christ. We also should not try to earn our salvation, by doing everything right or keeping the Law, which is not available that way. The Word of God clearly says, “that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.” Romans 10:9-10 (NKJV)
Salvation is attained by believing and confessing:
In the heart of one believes, that Jesus is the Lord and He rose from the dead and lives forever, this faith is accounted to him as righteousness. And with the mouth one confesses that Jesus is his Lord and Saviour, then his confession in front of other people gives him salvation. “But God, who is rich in mercy, because of His great love with which He loved us, even when we were dead in trespasses, made us alive together with Christ (by grace you have been saved), and raised us up together, and made us sit together in the heavenly places in Christ Jesus, that in the ages to come He might show the exceeding riches of His grace in His kindness toward us in Christ Jesus. Ephesians 2:4-7 (NKJV)
David:
David who lived under the Law, when he ended up committing sins, wanted to have grace from God desperately. He called those, whose lawless deeds are forgiven and whose sins are covered, as blessed people. Glory to God, we are given that privilege, who are under the Grace, to whom the Lord do not impute our sins, and we are the blessed according to king David. “For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.” Ephesians 2:8-9 (NKJV)
Escape from the curse of the law:
The very important thing we, who are in Christ Jesus, should be rest assured that our sinful thoughts or deeds never comes between God and us anymore. Even after we got saved sin try to creep in, but do not be condemned by that; which the devil wants to happen and to stop you from coming to the Lord with boldness or to serve Him in His ministries. But make sure that you are justified only by faith in the finished work done by the Lord on the Cross, because by keeping the Law no one is justified but rather come under curse. “For as many as are of the works of the law are under the curse; for it is written, “Cursed is everyone who does not continue in all things which are written in the book of the law, to do them.” But that no one is justified by the law in the sight of God is evident, for “the just shall live by faith.”” Galatians 3:10-11 (NKJV)
