What does the Bible say about the sufficiency of God?

In 2 Corinthians 3:5, Paul emphasizes that our sufficiency is not of ourselves, but it comes from God. This delineation draws attention away from personal merit and capabilities towards God's grace and strength. Paul frames the success of the gospel and ministry not in terms of human achievement but rather in divine enablement. All true ministers of the gospel acknowledge that any ability to preach or serve is a gift from God, highlighting the importance of divine sovereignty in Christian life.
