How do you answer a skeptic that complains that there is something wrong with the teacher when everyone in Christianity has a differing opinion? [Proverbs 25:2].
If you were wrong in the past about the meaning of some passages of scripture, how do we know you are now teaching the right thing? What will happen to those that were taught the wrong thing? [ I John 2:27, Proverbs 25:2, Acts 17:11, Psalm 19:10].
