I can’t say for sure, but I suspect that most people don’t think about heaven, because that would mean thinking about death. A healthy mind doesn’t dwell on death. Most people are thinking about today and planning for tomorrow, not the afterlife.
Hopeless people think of heaven as an escape from the pain of their lives. There’s a longing to be free of pain–anything but the pain. They’re not looking to what heaven really is, they just want out of where they are.
But people who grow close to God begin to see how amazing He is. He is powerful and good and so full of love. How awesome it must be to live in heaven where His presence is tangible everywhere. Where the fragrance of God fills the air. When we experience His peace and His joy, we want more. Who wouldn’t?
Heaven begins to call to us. For where your treasure is, there your heart will be also. (Mat 6:21) When your heart is with God, you want to be where He is. There’s a tug-of-war going on in you. As the Spirit of God gives you peace for your day, you also long to be where the Father is. Heaven is not an escape. It’s calling you home.
