God's authority governs and rules this world, and God is free to govern the way he wishes. This provides the foundation for the experimental nature of modern medicine. We may not presuppose how the world is or how God has chosen to govern it. Being healthy in a Christian way needs to investigate the world to distinguish patterns and regularities that exist as a result of God's governance. It may be the case that there are certain limitations that we simply accept as givens. Examples of limits may be life or non-life, human or non-human. Only human beings were created in the image of God and that is the reference given in bible.
God is always dynamically involved in our health. He acts in mysterious ways. Due to our sins, we no longer see God at work in the ordinary events of life. We separate ourselves and get diseased. Blood of LORD Jesus Christ can cleanse or sins and diseases and can give the Christian health we are longing for. “...the blood of Jesus Christ his Son cleanseth us from all sin.” (1 John 1:7) and even then we don’t understand. We ought to give out the extra sensory or supernaturals because it gives the impression that normally things occur according to their "natures" apart from the Divine governance. The distinction ought to be between ordinary/extraordinary or regular/irregular. Ordinary events are no fewer acts of God than miracles. In the miracle God does not act contrary to natural laws but contrary to his normal manner of governance. We are repeatedly ignoring his words and the result for example if we are diseased HE has to come out of his normal method of governance to save us. This is the Christian way to become healthy.
Satan also has the power to effect signs and wonders and healing miracles, and that they use that power to lead men astray from the true way of salvation (Exodus 7:10-11, 20-22; Exodus 8:6-7; 2 Thessalonians 2:9-10; Revelation 13:12-14). Deuteronomy 13:1-4 makes it clear that our faith should not be based on any sign, wonder, or miracle but on God's word. The Bible exhorts us to scrutinize everything (1 Thessalonians 5:21).healing particularly Christian healing is natural and that happens due to faith, an uncompromising faith in HIS words and that is the only way for Christian health and salvation
At Mt. Sinai, God gave Moses the Ten Commandments and many divine instructions about personal behavior, methods of worship and lifestyle choices. God ordered the Israelites not to eat certain types of animal flesh. The Israelites repeatedly disobeyed God's instructions. Therefore, if a person ate "unclean" food in Old Testament times, they were choosing to disobey God's instructions. The Old Testament dietary regulations are still found in Leviticus 11 and Deuteronomy 14 in Bible. Jesus Christ and his disciples followed the dietary laws. Jesus' support for God's Old Testament laws in Matthew 5:17-18 is very explicit evidence in the New Testament.
