Ben Sira 38:4, KJVA: The Lord hath created medicines out of the earth; and he that is wise will not abhor them.
Do not put all your faith in modern medicine, but instead in he who has created you. Prayer is good. Protect your mind from toxic mind-altering substances that damage your relationship with The Most High and His Spirit that resides in you. This can make your prayers ineffective.
Be careful what you are injecting or putting into your body, and read the ingredients. Remember, that there are many natural herbs that can be used for healing.
You body is a temple, so treat it as such and do not pollute it with unclean things, or dull your senses, lest you get misled.
1 Peter 4:7, KJV: But the end of all things is at hand: be ye therefore sober, and watch unto prayer.
