The following verses tell us that we are justified by faith in Christ:
John 5:Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life. Note the words hearing and believing that is faith!
Acts 13:39And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses.
Romans 3:30Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
Romans 5:1Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:
Galatians 2:16Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
It is through our faith in Christ that we stand righteous before God!
