And let them sacrifice the sacrifices of thanksgiving, and declare his works with rejoicing.
Psalm 107:22 (KJV)
Thanksgiving becomes a sacrifice anytime we go against our emotions. When we refuse to allow negative emotions to rule us, and instead focus on the goodness of God and the many things we may thank Him for, we are offering up the sacrifices of thanksgiving. A grateful heart will lead to a heart filled with joy, and out of a joy-filled heart we find ourselves declaring God’s goodness over our lives.
