Q1: “Double minded??” (not sur what exactly the question is. )
A: There is no different than a repented heart. Peter denied Jesus three times, but he was given a second chance.
What’s important here is NOT to dwell in the past. Don’t worry about the future either. Forget the past.
Proverb 24:16—Our Heavenly Father sees us righteous as long as we continue to rise.
Q2: To what extent are natural practices acceptable such as vitamins or eating habits? I assume all of these are part of walking in divine health.
A: See Section 9 of the DHT manual. Divine healing: The only way is God’s way.
Vitamins are fine, but God’s way is higher. Nothing can be added to divine healing.
It is always about where your faith is. Key distinguishing factor: Are you eating those supplements in fear? We are not called to live like merely mortal men.
Nothing wrong in eating right. What matters is to be in no fear, be in faith, and trust God.
