What does the Bible say about salvation being done rather than do?

The Apostle Paul contrasts the two systems of belief by describing a religion of 'do' versus a religion of 'done.' In Acts 13:12, the deputy believed when he saw what was done, pointing to the finished work of Christ. This pivotal moment illustrates that true faith comes from understanding that salvation is a completed act of God's grace, not a result of our deeds or efforts. As indicated in Hebrews 1:3, Jesus purged our sins by Himself, reinforcing that salvation's completion rests solely on His finished work, which we are called to accept by faith.
