The train-the-trainer framework turns people into subject matter experts so they are equipped to train others. The Lord has done that for us by giving us the scriptures. Philippians 4:9 says, “Those things, which ye have both learned, and received, and heard, and seen in me do: and the God of peace shall be with you.” Through his word, He has taught us what we need to teach others about Christ. God bless you!
