What does the Bible say about effectual mercy?

Effectual mercy is a term that emphasizes the successful and powerful nature of God's mercy. It is the mercy of God, capable of fulfilling His purposes without failure. This concept is illustrated through the exodus of the children of Israel from Egypt, which was not merely a historical event, but a demonstration of God's promised and purposeful mercy. The Israelites were delivered from bondage not because of their own worthiness, but through the effectual mercy of God that cannot be thwarted. This means that when God extends His mercy, it is certain to achieve its intended result: salvation and deliverance for His people.
