Whether you substitute “the Gates of Hell” or Satan into this passage, the message from Jesus is clear — God Wins!

Matthew 16:18
18 And I tell you, you are Peter,[a] and on this rock[b] I will build my church, and the powers of death[c] shall not prevail against it.[d]

Revelation 20:10
10 and the devil who had deceived them was thrown into the lake of fire and brimstone where the beast and the false prophet were, and they will be tormented day and night for ever and ever.
