In the beginning, we already had things to be thankful for.
At Genesis 1:1 We already had a Lord worth being thankful for, a Savior, and the Holy Spirit.
By day 6 of creation, everything you see what either created or thought of.
On Day 6 of creation, we were given the best command of all time.
By Leviticus 16, we had been introduced to 8 members of the Hall of faith (Heb 12) AND were given the picture of how Jesus would take our sin and we would walk
2 Samuel 7 we learn that the savior of the Lord is coming through the line of David
2000 years ago we were given the person to whom we could be the most thankful.
