When a Christian finds himself in a difficult situation, he should immediately give thanks to the Father, in the name of Jesus Christ, by the power of the Spirit, to keep his heart from complaining and fretting. The devil moves in when a Christian starts to complain, but thanksgiving in the Spirit defeats the devil and glorifies the Lord.
The word gratitude comes from the same root word as grace. If we have experienced the grace of God, then we ought to be grateful for what God brings to us. Thank and think also come from the same root word. If we would think more, we would thank more.
