"When I saw the truth that God is most glorified in us when we are most satisfied in him, I was freed from the unbiblical bondage of fear that it was wrong to pursue joy. What once had seemed like an inevitable but defective quest for the satisfaction of my soul, now became not just permitted but required. The glory of God was at stake. This was almost too good to be true—that my quest for joy and my duty to glorify God were not in conflict. Indeed they were one. Pursuing joy in God was a non- negotiable way of honoring God. It was essential. This was a liberating discovery. It released the energies of my mind and heart to go hard after all the soul-happiness that God is for me in Jesus."
