“To the angel of the church in Philadelphia write: These are the words of him who is holy and true, who holds the key of David. What he opens no one can shut, and what he shuts no one can open. I know your deeds. See, I have placed before you an open door that no one can shut. I know that you have little strength, yet you have kept my word and have not denied my name.” Revelation 3:7-8 NIV
When you are doubtful as to your course, submit your judgment absolutely to the Spirit of God, and ask Him to shut against you every door but the right one…
Meanwhile keep on as you are, and consider the absence of indication to be the indication of God’s will that you are on His track…
As you go down the long corridor, you will find that He has preceded you, and locked many doors which you would fain have entered; but be sure that beyond these there is one which He has left unlocked. Open it and enter, and you will find yourself face to face with a bend of the river of opportunity, broader and deeper than anything you had dared to imagine in your sunniest dreams. Launch forth upon it; it conducts to the open sea.
God guides us, often by circumstances. At one moment the way may seem utterly blocked; and then shortly afterward some trivial incident occurs, which might not seem much to others, but which to the keen eye of faith speaks volumes. Sometimes these things are repeated in various ways, in answer to prayer. They are not haphazard results of chance, but the opening up of circumstances in the direction in which we would walk. And they begin to multiply as we advance toward our goal, just as the lights do as we near a populous town, when darting through the land by night express.
