The Christian’s real home is where Christ lives. This gives us a different perspective on our lives here on earth. To let heaven fill your thoughts means to look at life from God’s perspective. This is the antidote to materialism; we gain the proper perspective on material goods when we take God’s view of them. The more we see the life around us as God sees it, the more we live in harmony with Him. We must not become too attached to what is only temporary.
