"If God blesses me, then I will serve Him." That's in your bible, but it has nothing to do with us.

Grace is not the law. Grace is not law lite. Grace is Grace and Law is Law. Each one has different rules, yet some are the same. We can not just pick the ones we like and claim them while rejecting the ones we don't like. When it comes to physical blessings we don't get any, but when it comes to spiritual blessing we are complete. Seeing and knowing the difference is the key as we live the Grace life unleashed. You're going to have to study your bible.
