Oh dear. I can't stop giggling at that title. I am hilarious. May your hallowe'en be filled with light and goodness. Make the most of the opportunities God brings to your door.
I am human and as such I like to tick boxes. I want to ensure that I'm doing all that I need to do to please God, and if praying-by-numbers is the right way, then that's what I'll do. But I don't... I can't. I can't please God by doing religious things. He's not a fan of that kind of thing.
It is not proud or arrogant to trust in God's forgiveness and live joyful lives. He has washed our sin away. Why would we hang on to the sin He has discarded?
