"What happened to 'it's more blessed to give than receive'?" you wisely question.
I can understand your thinking as A Christmas Carol and visions of the miserly Ebeneezer Scrooge transforming into a joyful giver come to mind.
But, before you dismiss William Willimon's quote consider it in light of these and then see if it makes more sense.
16"For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life." -- Jesus Christ
10Jesus answered her, "If you knew the gift of God and who it is that asks you for a drink, you would have asked him and he would have given you living water."
27"Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid." -- Jesus Christ
28"I give them eternal life, and they shall never perish; no one can snatch them out of my hand." -- Jesus Christ
32He who did not spare his own Son, but gave him up for us all—how will he not also, along with him, graciously give us all things?
23For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.
8For it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God— 9not by works, so that no one can boast.
As II Corinthians 9:15 declares,
"Thanks be to God for his indescribable gift!"
So be a joyful receiver of God's wonderful goodness!
