Romans 16.20The God of peace will soon crush Satan under your feet. (NIV)
The grace of our Lord Jesus be with you.

What an amazing prayer of benediction that Paul gave the Romans! do you believe God is all-powerful and all knowing among the world's woes and troubles. well, Good news, Jesus is coming back soon and all the evil will be dsetroyed. Just like how it takes time for a fruit to ripen before it is plucked and eaten, so is God allowing the evil and wickedness to ripen before he crushes Satan under his feet.
