Many believers have tremendous difficulties receiving the word of God. Consequently, finished work messages and godly investments do not profit them.
Many mental blocks come from past bad experiences.
Maybe someone was mistreated by a family member, or perhaps he had a number of failures at school or work. Moody people usually have mental blocks. They are happy one moment and depressed the next. They exalt what has happened in the past more than what God can do in the future. When mental blocks rise up against us, we must believe what God says about our lives.
