How do we know the atonement is free?

The atonement flows freely from the heart of God, as emphasized in the article. Just as the sun shines and the ocean waves crash without cost, God's love pours forth unconditionally and freely through the cross of Christ. The nature of the atonement excludes any need for human merit or righteousness. It is meant for sinners and the undeserving, as Romans 5:6 states, 'For when we were yet without strength, in due time Christ died for the ungodly.' Therefore, the foundation of our acceptance lies in God's grace alone, emphasizing the freeness of His provision to the most unworthy among us.
