Gratitude is not only what we say, but how we act. How we treat the gifts we have received is usually a reflection of how thankful we are for the gifts.
“As ye have therefore received Christ Jesus the Lord, so walk ye in him: Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving. (Colossians 2:6-7|KJV)
A grateful life is one that overflows with thankfulness not grumbling. A grateful life is also a careful life, jealously guarding the gift of Christ they have received.
