Read Psalm 148
Praising God is an act of obedience. It is not about how we feel or the circumstances around us. We praise Him because He commands it.
Choose a characteristic to praise God for today. Write it on a sticky note or even on your hand like a temporary tattoo. (Yes, it might sound crazy but a word written on your hand is a constant reminder.)
As you go about your day, whatever comes your way: joys, struggles, pain. Take a look at your word and praise Him.
What did you experience by praising Him throughout the day?
