So, living a healthy life is very important. 200 years ago, ministers of Christ like John are concerned about the health of people.
As it is said in the scripture in 3 John 1 verse 2 says, Beloved, I wish above all things that thou mayest prosper and be in health, even that is so prospered.
This shows that, although this is a common knowledge, but people among scientists are also good, and our health has deteriorated because we are not taking our health seriously.
According to the Bible, the common knowledge of people is that our health will deteriorate no matter what. But by staying healthy and eating good food, we increase our chance of living a healthy life.
The health of a person can prosper, even that is so of Christians also prosper. So, physically, spiritually, we need to be fit and stay healthy. So, we should avoid addiction of alcohol, tobacco, and anything that deteriorates our health.
But I tell you, about accepting that teaching of God is very important. And Jesus Christ will not stop, totally. So, all those things that affect our health and make us to prosper, it is very important that we also learn those habits to save us from everything that is holding us down.
