(Proverbs 28:7 KJV) Whoso keepeth the law is a wise son: but he that is a companion of riotous men shameth his father.
A believer “keeps” (5341) the “law” (8451). I know that goes against our Protestant mantra of being under grace and not the law. We are under grace. So was Noah. Grace is not a New Testament concept. It was not a new idea with the Apostle Paul.
And the Law is not just an Old Testament concept. Jesus spoke a lot about obedience and never about grace.
So what does it mean to keep the law? This word means to “watch, guard, keep.” It is much deeper than just following rules. It involves making sure that standards are maintained. It means obedience. Notice that it is the product of a “wise” (discerning NASB) (995) son. The contrast would be the fool.
So? Put some energy into walking straight. We can do nothing without the grace of God but He seems to infer that He expects us to do our part, whatever that is to you.
