In this message, The Heart of a Mentor, walking verse by verse through First Thessalonians to reveal the marks of faithful, Christ-centered leadership. Facing criticism, Paul points to a ministry free from doctrinal error, impure motives, deception, flattery, greed, or a desire for man’s praise—declaring instead that he speaks “not as pleasing men, but God, which trieth our hearts.” Anchored in the coming of Christ (1 Thess. 1:10; 4:16–17), Paul models a servant willing to “spend and be spent” (2 Cor. 12:15), to nurture believers with the tenderness of a mother and the firmness of a father (1 Thess. 2:7, 11–12), to wrestle in spiritual battle (Eph. 6:12), and to labor continually in prayer (1 Thess. 1:2–3). This sermon challenges every believer—especially those in ministry—to examine our motives, invest sacrificially in disciples, and live in light of the Lord Jesus Christ’s return.
