"You must serve the LORD your God, and he will bless your food and water. I will take away all sickness from among you". Exodus 23:25 (God's word translation)

The best way to stay healthy, and have God's blessings on your life is to serve God. to worship Him. to do His bidding, and to seek to please Him.
Serve Him with your strength, serve Him with your money, serve Him with your time, serve him with your live. for this is why you were raised. you were raised to serve God, and in serving him, you will be rewarded with blessings, and good health. sickness will be far from you and your family,
and you will know the kind of peace that only God can give.
