Isaiah 6:2-3 NKJV
[2] Above it stood seraphim; each one had six wings: with two he covered his face, with two he covered his feet, and with two he flew. [3] And one cried to another and said: “Holy, holy, holy is the Lord of hosts; The whole earth is full of His glory!”
When you see someone dressed nicely, it's complimentary to tell them you are impressed by their appearance. I often tell my wife how nice she looks when all dressed up, even at times when she's without makeup and in her pajamas. It's because of my love for her, no matter what she's wearing, she's beautiful to me.
In Heaven there are seraphims (or Angels), who are constantly praising God and recognizing His holiness. As humans it might be difficult to understand how worshipping God 24/7 can happen, but I believe once in the presence of God, we all will recognize His beauty, His holiness, and His love for each of us.
Until that time, I think we all need to feed our minds with scriptures that reflect His character so we can be prepared to worship Him, alongside the Angels who reside by His side throughout eternity. As you come to know Him more, give Him the praise and recognition He rightly deserves. God is good, all the time! What more reason do you need to give Him praise?
