When God seems to be taking too long, it’s not because He’s got more than He can handle? If God could be detoured, overwhelmed, confused, disorganized, or prone to biting off more than He can chew, He wouldn’t be God, He would be a man.
God answers prayers in mysterious ways sometimes? Often when He chooses this method the answer to the prayer is not obvious. Additionally, his response may not materialize in actions, consequences or blessings immediately. It could take seconds, even decades.
Trust in the LORD with all thine heart; and lean not unto thine own understanding.  In all thy ways acknowledge him, and he shall direct thy paths. Proverbs 3: 5-6
