Timothy may have been a kingdom kid, but that does not mean he knew it all. Paul mentored him, especially when he was put into a leadership position. He had a very strong spiritual upbringing with both his Mom and Grandmother being disciples, but that does not guarantee that he will have the same spiritual values. He had to learn the on his own. Whether you have come into the kingdom fresh, or live among it all your life, God still needs to be a personal relationship for you.
