But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they.  (Acts 15:11 KJV)

(23) for all did sin, and are come short of the glory of God—  (24)  being declared righteous freely by His grace through the redemption that is in Christ Jesus,  (25)  whom God did set forth a mercy seat, through the faith in his blood, for the shewing forth of His righteousness, because of the passing over of the bygone sins in the forbearance of God—  (26)  for the shewing forth of His righteousness in the present time, for His being righteous, and declaring him righteous who is of the faith of Jesus.  (27)  Where then is the boasting? it was excluded; by what law? of works? no, but by a law of faith:  (28)  therefore do we reckon a man to be declared righteous by faith, apart from works of law.  (29)  The God of Jews only is He , and not also of nations?  (30)  yes, also of nations; since one is God who shall declare righteous the circumcision by faith, and the uncircumcision through the faith. Romans 3:23-30 YLT  

Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)  (Ephesians 2:5 KJV)

For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:  (Ephesians 2:8 KJV)

Who hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began,  (2 Timothy 1:9 KJV)
