God is the keeper of the door, He allows what comes in and what goes out.
John 10:9 - The first door we should seek to open it that of the kingdom of God. Matthew 6:33 also said seek ye first the kingdom of God and everything else will follow. This is the entry to all open doors for anyone that will be enter into God's provision for their life.
The door is open, God has the key to open and close all doors as He sees fit for anyone who is committed into His hands. Matthew 6.33 said " seek first the Kingdom of God and everything else shall be added...." This a promise to everyone who decides to seek God's kingdom to come over his or her life. The door is open to let God's kingdom come... Will you come in?
God determined what door to open to us and When. We can be rest assured that According to Jeremiah 29:11,whichever door God chooses to open or close are all for our good.
