Why is preaching Christ considered the primary duty of a servant of the Lord?

In 2 Timothy 2:24-25, Paul emphasizes that the servant of the Lord must be gentle, apt to teach, and patient, ultimately pointing to the necessity of preaching Christ as central to the ministry. This task transcends mere educational or charitable acts, as the proclamation of Jesus and His finished work is where genuine life and transformation reside. By focusing on Christ, the servant aligns with the divine intention of God's redemptive plan, facilitating others' understanding of grace and their subsequent response in faith.
