Colossians 2:6-7 (New International Version)
6So then, just as you received Christ Jesus as Lord, continue to live in him, 7rooted and built up in him, strengthened in the faith as you were taught, and overflowing with thankfulness.
Do you experience giving thanks primarily as a response to positive situations, or as a discipline?
What purpose might the discipline of giving thanks play in your being rooted and built up in Christ.
Make a list of those things for which you are thankful, and then give thanks for them. (The list may even contain painful things.)
