Therefore

This is the time of year when we focus on being thankful. This is where it begins:

"But when this perishable will have put on the imperishable, and this mortal will have put on immortality, then will come about the saying that is written, 'Death is swallowed up in victory. O death where is your victory? O death where is your sting?' The sting of death is sin, and the power of sin is the law; but thanks be to God who gives us the victory through our Lord Jesus Christ.
Therefore (this is how you "tell" Him you're thankful), my beloved brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that your toil is not in vain in the Lord."

Yes, thankfulness is a life style. "In everything give thanks, for this is the will of God in Christ Jesus."

How thankful are you for "the victory through our Lord Jesus Christ"?

If someone spent just one day with us--maybe just one hour--I bet they would know.
