Building a church is costly. It takes resources to build anything. You can’t build much for free. There will always be an element of personal sacrifice and costliness when you attempt to build something. And there is a price tag for building a community where the presence of God dwells. It was the same in Moses’ day too.
What enables you to worship God through the giving of your time, talent and treasure with true joy? Why would you joyfully give yourself away for the kingdom of God? There never seems to be enough time, talent or treasure to go around anyway. So why would you joyfully give these things away instead of keeping it to yourself?
