The Message paraphrases James 3:1, "Don’t be in any rush to become a teacher, my friends. Teaching is highly responsible work. Teachers are held to the strictest standards. And none of us is perfectly qualified." Teaching is rewarding work, even as it is draining physically, mentally, and spiritually. Teaching can have powerful impact on lives, even while we may feel a failure.
Considering the importance of teaching, the various methods one should employ, the purpose of life change, etc. could cause us to give up due to intimidation. But we must not cower to fear; God has called you to a great ministry. Therefore, as Apostle Paul challenges us in Romans 12:6-8, let's be faithful to perform it to the best of our ability. We will never be perfect, but God will use even our imperfections to His glory.
Thank you, teachers, for your labor of love and faithfulness in service!
