If God shuts a door, quit banging on it! Whatever was behind it, wasn’t meant for you. Consider the fact that maybe he closed that door because He knew you were worth so much more.
Sometimes I don't understand why things happen the way they do but I know in the end that God has a plan.
God has a reason for allowing things to happen. We may never understand God's wisdom but we simply have to trust God's will. God bless you all the way.
