“To relish and rejoice in the beauty of God alone accounts for why we exist. Enjoying God is the soul’s sole satisfaction, with which no rival pleasure can hope to compete. Glorifying God by enjoying him forever. It’s the Christian Theory of Everything.”-Sam Storms
“These things I have spoken to you, that my joy may be in you, and that your joy may be full.”–Jesus (cf. John 15:11)
Trying to explain this to someone who has never experienced the true joy of knowing and loving God is very difficult. It is like trying to describe a fillet Mignon steak to someone who has never eaten one. But that is what we try to do. We invite those who don’t know God to taste and see. Much of Christian understanding is preceded by experience (though both are necessary for the knowledge of God).
