You are correct. It’s a hard subject but I make a point of attacking and teaching hard subjects. Anyone who teaches Sunday School seriously, knows that you learn much more than the class does in the process of preparation. Everybody has their gift that God has given them and mine is researching, understanding and teaching scripture. I really love doing it as does everyone when it comes to their own spiritual gifts.
Two very good lines of inquiry (never see it taught this way, though); both lead to the Trinity:
1. Who raised Jesus from the dead?
2, Who comes to indwell the believer?
