How do we know salvation is all of Christ?

The Scriptures affirm that salvation is entirely a work of Christ’s grace, as highlighted in Galatians 2:16, where Paul asserts that justification cannot be attained through works of the law but is received by faith in Jesus Christ. This underscores the sovereignty of God in salvation; it is not a cooperative effort between human will and divine grace. Christ, who is faithful and true, accomplished our salvation, ensuring that all who trust in Him are made perfectly whole through His sacrifice.
