Habakkuk 2:14 is the ultimate truth. “For the earth will be filled with the knowledge of the glory of the LORD as the waters cover the sea.” 

No man can change that. The knowledge of the glory of the LORD will cover the earth.  Though the world may be in chaos, the body of Christ is in its finest hour. You carry the glory of God and are His salt and light in the earth.  Don’t be a closet Christian. Let the world around you see His glory. Expect to be a part of the answer and refuse to dwell on all the problems in the world.  Dwell on the King who has come to reconcile all men to God and follow Him.
