Charles H. Spurgeon said, "Men need to be told that, unless divine grace brings them out of their enmity to God, they will eternally perish." He went on to say "that if they are to be saved, it must be by grace, and by grace alone."
We are not saved by our works (Titus 3:4-5). If salvation is by works, we could boast of what we have done. However, salvation is by the grace of God, which means it is the gift of God (Ephesians 2:8-9). Salvation is the finished work of our Lord Jesus Christ. We are saved by grace through faith in Christ, to the glory of God!
Spurgeon knew that if we are saved, it's not by grace plus our works. Many teach that salvation is initiated by God's grace and must be completed by our works. Not so. We are saved by God's grace alone. His grace begins and completes our salvation in Christ (Philippians 1:6).
We are saved by grace through faith in Christ. Faith receives the gift of God in Christ. The gift of God is the grace of God, found in Christ alone (Acts 4:12). He alone died for our sins. He alone is risen from the dead as our living Lord. Grace is trusting the finished work of Christ for us, and the work of Christ in us. We are saved by grace, as the gift of God in Christ (Ephesians 2:8-9).
