The following happens when the heavens are closed to someone:
Failure, poverty, regression, rejection, sorrow, curses, unanswered prayers, sickness, etc. It is impossible to prosper and fulfill destiny when your heavens are closed. How do we open our heavens? Pray without ceasing-Jesus prayed and the heavens opened to him! Your level of prayer life determines how wide your heavens will be opened to you. Open heavens signify rain from heaven- when there is no rain on a land, the result is unfruitfulness. That is why Elijah cried mightily to God for open heavens over the land.
Sin will also close your heavens; obey God always to enjoy open heavens.
