We are righteous by faith in Christ’s obedience and not by our works.
Romans 5:18-19 “Therefore, as through one man’s offense judgment came to all men, resulting in condemnation, even so through one Man’s righteous act the free gift came to all men, resulting in justification of life. For as by one man’s disobedience many were made sinners, so also by one Man’s obedience many will be made righteous.”
But how did Christ’s obedience make us righteous?Jesus Christ came to obey the law and end it.
Romans 10:4-10 “For Christ is the end of the law for righteousness to everyone who believes. For Moses writes about the righteousness which is of the law, “The man who does those things shall live by them.” But the righteousness of faith speaks in this way, “Do not say in your heart, ‘Who will ascend into heaven?’ ” (that is, to bring Christ down from above) or, “ ‘Who will descend into the abyss?’ ” (that is, to bring Christ up from the dead). But what does it say? “The word is near you, in your mouth and in your heart” (that is, the word of faith which we preach): 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.”
Why did the law end with Jesus? Its because the law demanded perfect obedience.
Jesus is the only one who perfectly obeyed the Sermon on the Mount without any sin.
That’s because even one sin under the law would make us all guilty. A person had to do all the things in the law to be righteous.
But nobody could do it except Jesus.None of us can behave like Jesus.
He perfectly obeyed the law for our sake.
The law demanded death for man’s disobedience – Jesus died for us, and rose from the dead, ending the law, so that we are righteous simply by faith in Jesus and not our works.
Our works are disobedient, but Christ’s obedience made us righteous by grace through faith.
