You'll never trust a person if you never spend time with them. If you don't trust someone, you'll never let them know the REAL you. This limits your growth and limits your ability to help them grow. You hinder yourself and everyone else around you. This is one of the main reasons that church people struggle so much. They're isolated, cut off from the other members of the church. They are within the same proximity as other Christians but their lack of connection is hindering their growth.
