If you choose to enter a state of worship, the first thing you may encounter is an unworthiness or a reluctance to receive love. This is natural. When you acknowledge your own divinity and the indissoluble connection of your divinity with the Source of All, something is going to scream. What screams is every part of you that has hidden for shame. Worship brings these parts blinking into the light and expecting punishment.
There is no punishment. You are innocent in the eyes of God, whatever you have done or not done. A jewel is no less a jewel for having picked up some mud on its travels. But for you, to know that you are innocent is a skill. This skill can be acquired through worship.
