What the Bible says about Unmerited Pardon
(From Forerunner Commentary)
Christ moved with compassion on behalf of a person who, from the world's viewpoint, was repulsive and undesirable, totally unappealing in any situation. Jesus did not cleanse him because he was nice-looking or wealthy. Similarly, God does not choose to call us into His church due to our good works, beauty, or money; in us is nothing spiritually appealing. Spiritually, we are like the leper was physically—repulsive and undesirable in terms of holiness. We can thank God that His grace "brings salvation" (Titus 2:11) and "by grace we are saved" (Ephesians 2:8). God does not call us to salvation because of what we are but because of what He is. According to His mercy, God decides on whom to have compassion (Psalm 86:15; Romans 9:15-16).
