One of the key tenets of our faith is that through Christ and Christ alone we are saved. Galatians 2:20-21 says it as clear as anywhere in the Bible, 20 I have been crucified with Christ and I no longer live, but Christ lives in me. The life I now live in the body, I live by faith in the Son of God, who loved me and gave himself for me. 21 I do not set aside the grace of God, for if righteousness could be gained through the law, Christ died for nothing!” If we could do anything by our own power, then Christ died on the cross for nothing.
