Here's a quote from the last chapter, The Hope of the Gospel.
On the days when you feel as though you'll never get it, you'll never please [God], you're such a failure, you must remember the lavish gift: [Jesus'] great heart pumped blood through his veins and then out his wounds so that he could bless you. This perfect blood streamed down his body and tumbled through space, pooling on the earth beneath his feet. It was trampled on by those who stood below jeering. It mingled with the dirt he had created, and from it grew your hope. And then, on the days when you believe you're finally getting it, finally pleasing him, when you think you can look in satisfaction at your goodness, you'll need to look at that blood even more closely. Take yourself to Calvary and stand there until all your good works seem to you as they really are: vile sludge purified only by his cleansing flow.
- p. 190, from Because He Loves Me by Elyse M. Fitzpatrick
Also, the appendix of the book contains a personal testimony and evangelistic message from the Elyse M. Fitzpatrick, which I thought was excellent.
