In short the reason why a person has a lack of Peace, Hope or Love and therefore can’t relax and rest is generally from what I have found a lack of understanding about God, God’s Grace, God’s Love and the position that His Amazing Grace and the “Gift beyond compare” of Jesus Christ places them in.
“In the beginning God created the heavens and the earth.” Genesis 1:1
“In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of all mankind.” – John 1:1-4
I hope this simple picture will help you understand why most churches create non-relaxation or temporal relaxation at best!
