One of the greatest impediments to thanksgiving is worry. People who are always fretting about one thing or another cannot give their best expression of gratitude to God. Chronic worriers need to show more faith in the Lord. Jesus has quite a lengthy section in the Sermon on the Mount about avoiding the sin of worry.
What is it that you are anxious about? Don’t let your anxiety take away the peace that God wants all his children to experience. By trusting God more, you can open up new avenues of expressing gratitude to the One who created you, who offers you salvation through the crucified and resurrected Jesus and who showers you with countless blessings every single day.
“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
