Hello ,
Have you ever had a day when you didn't feel like praising God; a morning when it took all that you had just to get out of bed? It's a very human thing to rely on our feelings, but nowhere in this passage of scripture does it say that we are to praise God as long as we feel like doing it.
Human emotion is unreliable, but God is eternal and unwavering. Let me challenge you to take out 5 minutes, and write a quick list of all the blessings that God is giving to you today. If you're anything like me, it won't take long for us to recognize that He is worthy of any and all praise that we can humbly bring to Him.
Have a great day and God bless!
