When two opposing views are held with deep conviction inside the same mind, the internal turmoil this creates will cause an unstable mind.
God created the world miraculously and it evolved too = unstable mind rises.
God created beautiful marriage for family and two men or two women can make a marriage = unstable
Jesus commanded baptism and that makes it important BUT not necessary for salvation = unstable mind ensues.
God is good and righteous but I am angry at Him from time to time for Him allowing me to be harmed = unstable mind at work.
When we have a unified world view based on God’s Word, there will be peace in mind, body, heart, and soul.
