Let the peace of Christ rule in your hearts, since as members of one body you were called to peace. And be thankful. ~ Colossians 3: 15
A heart of gratitude is at the core of joy and happiness. Happy is the man who understands how to acheive daily gratitude.
Those pesky dark habits also lose a foothold in our lives when we start with gratitude and walk with a heart of thankfulness for all God has done for us.
What if the only things you posessed today were the things for which you thanked God for yesterday? What would remain? What should remain?
