I get some of the strangest questions, but I think they are often questions that many people think, even if only a few verbalize them.
Q: So, if keeping God’s law means as much as not keeping God’s law, why keep it?
A: That is like asking, now that I’m married why do I attempt to please my wife? If I displease my wife does that mean that I am unmarried? No, the state of marriage is not made nor unmade by my keeping of the “honey-do list”. Similarly, our relationship with God is forged by our acceptance of His work on our behalf. It is not made by our keeping of His commandments, nor is it unmade by our failure to keep His commandments, and yet it is still true that “If you love me, you will keep my commandments.”
I think this is precisely the type of thinking St. Paul had in mind when he penned:
What shall we say then? Are we to continue in sin that grace may abound? By no means! How can we who died to sin still live in it?
(Romans 6:1-2 ESV)
