I hope this quotation from J. I. Packer will help you prepare for Thanksgiving:
“Appreciate the goodness of God. Count your blessings. Learn not to take natural benefits, endowments and pleasures for granted; learn to thank God for them all. Do not slight the Bible or the gospel of Jesus Christ, by an attitude of casualness toward either. The Bible shows you a Savior who suffered and died in order that we sinners might be reconciled to God; Calvary is the measure the of the goodness of God; lay it to heart. Ask yourself the psalmist’s question—’How can I repay the Lord for all his goodness to me?’ Seek grace to give his answer–’I will lift up the cup of salvation and call on the name of the Lord…O Lord, truly I am your servant… I will fulfill my vows to the Lord’ (Ps 116:12–18).”
—J. I. Packer, Knowing God, 165
