Who Filled You?

If God's Spirit, the Holy Spirit lives in you, are you still required to attend studies to learn about God, the Father?

But it was to us that God revealed these things by his Spirit. For his Spirit searches out everything and shows us God's deep secrets. No one can know a person's thoughts except that person's spirit, and no one can know God's thoughts except God's own Spirit. and we have received God's Spirit (not the world's spirit), so we can know the wonderful things God has freely given us.

But people who don't have the Holy Spirit cannot understand these truths from God's Spirit. It all sounds foolish to them and they can't understand it, for only those who have the Holy Spirit can understand what the Spirit means. 1 Corinthians 2:10-11, 14
