When we do what God ask us to do, and not deny his name, He rewards us.

When God opens a door for us, no man can shut that door. Man can not take away something that God has given us.

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.
