What does the Bible say about the ministry of the New Covenant?

In 2 Corinthians 4:1-6, the Apostle Paul emphasizes that this ministry is rooted in the New Covenant, distinct from the old covenant of condemnation. In verse 6, Paul proclaims that God has made us able ministers of this New Covenant, which signifies a transition to a ministry characterized by the Spirit's power and the righteousness of God. This ministry not only transforms lives but also reveals how God justifies sinners through faith in Jesus Christ, highlighting the glory of His grace.
