You have heard it said that “one man’s cult is another man’s religion”… This is only true to the natural mind; however, the Bible teaches in Proverbs 3:5 “Trust in the LORD with all thine heart; and lean not unto thine own understanding.”
Our relationship with the Lord is key, as in Psalm 37:4 “Delight thyself also in the Lord: and he shall give thee the desires of thine heart”. This is not “necessarily” speaking about fleshly desires of the heart, rather it is speaking about being shown the infinite mercy, love, and truth in being grounded in the Lord, and sometimes in receiving what we desire.
This is a spiritual condition which only the Lord can show us, (often in doctrines) and is not found in the futility of our natural understanding.
