Interpretation of verse 5-14
I believe God is talking about our prayer (Joyous Service). If our minds are sincere or free of dusts, God will accept our prayer to save the world. These blessings are God’s guidance to help others otherstand the heart. These dusts we must sweep from our minds are greed, arrogance, self-love, regret and covetousness.
