Love opens doors because God will get behind it and push them open.
To the church at Philadelphia
Rev. 3:8
To the angel of the church in Philadelphia write: These are the words of the One who is holy and true, who holds the key of David. What He opens, no one will shut; and what He shuts, no one will open. I know thy works: behold, I have set before thee an open door, and no man can shut it: for thou hast a little strength, and hast kept my word, and hast not denied my name.
