When God opens a door, that no man can shut, we still believe that man can shut it.
Because we keep trying.
No man can stop what God has for you.
Revelation 3:8 (KJV) – 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.
