Augustine reflecting on his conversion from a life of pride and sexual immorality to faith in Christ:
Suddenly it had become sweet to me to be without the sweets of folly. What I once feared to lose was now a delight to dismiss. You turned them out and entered to take their place, pleasanter than any pleasure but not to flesh and blood, brighter than all light yet more inward than any secret recess, higher than any honour but not to those who think themselves sublime. Already my mind was free of 'the biting cares' of place-seeking, of desire for gain, of wallowing in self-indulgence, of scratching the itch of lust. And I was now talking with you, Lord my God, my radiance, my wealth, and my salvation.1
His words remind me of what the Apostle Paul wrote to the church in Philippi.
But whatever gain I had, I counted as loss for the sake of Christ. Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith— that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death, that by any means possible I may attain the resurrection from the dead (Philippians 3:7-11, ESV).
