What does the Bible say about able ministers?

In 2 Corinthians 3:6, Paul emphasizes that it is God who makes ministers able to preach the New Testament, not of the letter but of the Spirit. This highlights that true ability to minister comes from God’s power and grace. Ministers are not self-commending; instead, their worth is derived from their calling and their reliance on God, who empowers them to declare the gospel faithfully. As Paul states, the letter kills, but the Spirit gives life, indicating that genuine ministry must be rooted in the Holy Spirit’s transformative work.
