Right Standing Through Faith Alone
And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith: – Philippians 3:9
Righteousness, being in right standing with God, is not through our law keeping but through faith in God, in what Jesus did on the Cross. We cannot earn our salvation, our right standing with God, on our own. It can only come through Jesus and what He did at the Cross because God requires a perfect Sacrifice, which is Jesus.
