A.W. Tozer on having God and nothing else:
God made you in His image and you’re stuck with it, sinner and Christian both. You’re made in the image of God, and nothing short of God will satisfy you. And even if you happen to be one of those “nickle-in-the-slot, get saved, escape hell and take heaven” Christians (that poor little kindergarten view of heaven), remember one thing– even you will find over the years that you are not content with “things plus God.” You’ll have to have God minus all things.
You may ask me, “Don’t you have things?” Sure I do. God knows that I don’t have much, only a lot of books. I have a wife and some children and grandchildren and friends– I have all that.
But as soon as I set my hopes and comforts upon things and people I’ll lose something out of my heart. It dare not be things and God, it dare not be people and God; it must be God and nothing else. Then whatever else God gives us, we can hold at arm’s length and hold it dear for Jesus’ sake. And we can love it for His sake, but it is not necessary to our happiness. If there’s anything necessary to your eternal happiness but God, you’re not yet the kind of Christian that you ought to be. For only God is the true rest.
