Closed doors simply means God is protecting us from having not the best.
What you subconsciously want, you will get. And what you subconsciously do not want, you will avoid.
Live uncluttered lives so you could have time for what is most important.
All of us prepare our own lunch. If we don't like our jobs, if we don't like the state of our relationships, if we don't like what's happening to our spiritual lives - we have no one to blame but ourselves. Because God has given us free will.
Don't try to get all your rewards on earth. There are more rewards in Heaven.
Your deepest pain will be your most Glorious Blessing.
