Isaiah 59:21 (NKJV)
21 “As for Me,” says the Lord, “this is My covenant with them: My Spirit who is upon you, and My words which I have put in your mouth, shall not depart from your mouth, nor from the mouth of your descendants, nor from the mouth of your descendants’ descendants,” says the Lord, “from this time and forevermore.”
There was once a boy who imagined that when he was 18, he wouldn’t have to do any of the things his parents had taught him when he was young. This boy was particularly irked that his parents made him brush his teeth each evening. Getting the toothbrush out of the drawer, squeezing the tube, brushing for a minute – it was all such a nuisance, so time consuming. And what was the value of it anyhow? He just ate the next day and got his teeth dirty again. What’s the point!
Eagerly the lad awaited his 18th birthday. His 16th came and went; his 17thcame and went; and finally, his 18th birthday arrived. He was free. He got a job, moved out of his parents home, and commenced his long coveted practice of not brushing his teeth.
Ah, he thought with pleasure on his first night in his new apartment, this is the life. No one to tell me what to do! No more brushing my teeth! Joy and gladness wrapped their way around his heart. And joy and gladness stayed with him – for a time. But soon he began to experience the consequences of his decision. His teeth took on a decidedly brown appearance; he found it hard to get a date; his teeth began to ache from the cavities that filled them. In the place of joy and gladness came doubt; in the place of doubt, frustration; in the place of frustration, anger; in the place of anger, despair. Until the day he found himself facing the mirror, extracting his long-neglected toothbrush from the drawer, scrounging for that toothpaste tube with the dried paste around the top, squeezing the requisite amount onto his brush and scrubbing with all his might. But try as he might, he couldn’t get those stains off and he couldn’t fill those cavities.
Many suppose that the reason God has poured out His Spirit upon us is to free us from observing God’s moral law. “The Spirit has come, we no longer need the law.” Such people are foolish and naïve, totally misrepresenting the relationship between the Spirit and God’s moral law. The Spirit was given not to deliver us from God’s moral law but to deliver us to His law – to give us hearts that want to obey it. God’s law is not the problem; we are the problem. Though God’s law is good and wise, we imagine ourselves wiser than God and reject His precepts. But we merely display our foolishness, showing ourselves no wiser than our non-toothbrushing teen.

We have done this as a society – endeavoring to replace God’s law for sexuality, marriage, and divorce with our own precepts – but more tragically we continue to do this as the people of God – picking and choosing which portions of God’s law to obey. So reminded that we frequently pit God’s Spirit against His law, that we frequently imagine that maturity means freedom from responsibility rather than the love of the same, let us kneel and let us confess our sins to God.
