But it didn't mean "Only on Sunday, we praise God." When we pray, when we start our day, when we are doing our activities, when we end our day; in all those we should remember to always give thanks.
Even though, we might be troubled. Always give thanks! It's not an easy task to do, but I believe that God would not leave us in lurch.
For the Lord is good. His unfailing love continues forever, and His faithfulness continues to each generation. - Psalm 100 : 5
I believe because He promised us. Hang on to His unfailing love and faithfulness.
