We must learn to always be thankful. Whatever state we are in, we must be content in whatever state we are in. One of the things that grieves the Holy Spirit is murmuring and complaining. God opened up the ground and swallowed the people perished because of it. What has opened up and swallowed you up because of complaining?
Thanksgiving is being appreciative despite of favorable circumstances. That is why it is called a SACRIFICE of praise! Praise and thanksgiving is worshipping the Lord! Praise confuses the camp of the enemy! The enemy desire is to for us to give him a legal right to hold our murmuring and complaining against us in the Courts of Heaven! We must replace our complaining with thanksgiving! I will bless the Lord at all times: His praise shall continually be in my mouth (Psalms 34:1)!
In closing, the songwriter said, "No matter who or what we are, we must praise!" Praise and thanksgiving is worshipping God. Our God is greater than what we are going through! Thank you Lord, thank you Lord, thank you Lord!
