"I blundered headlong into the love which I hoped would hold me captive, but in your goodness, O my God, my mercy, you sprinkled bitter gall over my sweet pursuits." - Augustine
My memories used to be painful for me, they reminded me of what I lost. Now, I thank God for them, because I am grateful for the mercy God has shown me in allowing me to have such good things to remember in the first place.
