And because of this great price, we are told to do what? Glorify God in your body and in your Spirit, which are God’s. 1 Corinthians 6:20
That is, you – your flesh, your thoughts, your mind – they all belong to God. And thus, you are to glorify Him, and not use your body for sinful purposes.
Right there is the motive for taking care of yourself physically. Knowing that our bodies are the temple of God, and that we have been told to glorify God in your body, it makes sense that we should take care of our health, and take care of our bodies in a way that will glorify God.
What is more likely to glorify God – abusing your body with drugs, alcohol, tobacco, and unhealthy food and bad lifestyle practices – or living a moderate and temperate lifestyle that will help you achieve the best health possible?
No question, as long as we are here – in fallen flesh – we are going to face sickness, ailments, and – unless we’re alive when Jesus comes – death.
But, because our bodies are gifts from God, we have a moral obligation to do what we can to take care of them the best we can. Just as hand-made gifts from friends have that added value, so it is with our bodies – hand- made gifts from God.
And though the Bible itself doesn’t present any kind of systematic treatise on health, we can take from it certain broad principles that can make a big difference in the quality of our existence here.
