Because nothing is greater and we have no greater need, God gives God.
The message of Christmas is not that we can make peace. Or that we can make love, make light, make gifts, or make this world save itself. The message of Christmas is that this world’s a mess and we can never save ourselves from ourselves and we need a Messiah.
God gives the world enough of what it needs. All He asks is that we distribute what He gives.
You can give up the need to compete in the world- when you accept being complete in Christ.
