And you must love the Lord your God with all your heart, all your soul, and all your strength.
-Deuteronomy 6:5 (NLT)
We all have some passions in life. Why not pour your passion into God? What does that entail? Just think about the actions you take when doing something that you love.
You think about it all day. You want to spend all your time on it. You put it first above all other things.
Now channel all those actions towards God and you will see grace filter through your day leaving behind anger, guilt and selfishness.
