"but I would create one that doesn't wear out, doesn't need replacement, and doesn't need me (God) as a crutch."

Well, that is exactly what he did if you believe what the Bible says about Heaven.

Who needs God as a 'crutch'? Is a child's parent a 'crutch' to him\her? I guess some kids do use their parents in that way (as some use the gov't that way too) - but with God and with a healthy family, the relationship is based on love.
