I have heard atheists say that God is an ego-maniac, because he wants praise. But these same people freely praise a music artist for some song they wrote, for example. Yet God gave that artist that ability.
Those same atheists would have hurt feelings if they accomplished some great thing and did not receive credit or recognition for it, or, someone else got the credit. But the God who created the amazing universe is not entitled to have those same feelings?
“but you have exalted yourself against the Lord of heaven; and they have brought the vessels of His house before you, and you and your nobles, your wives and your concubines have been drinking wine from them; and you have praised the gods of silver and gold, of bronze, iron, wood and stone, which do not see, hear or understand. But the God in whose hand are your life-breath and your ways, you have not glorified.” God’s message to King Belteshazzar of Babylon, Daniel 5:23
“The God who created the world and everything in it, being Master of both heaven and earth, he does not settle in shrines made with hands. Nor is he served by human hands as though he needed anything- he is the one who gives to all, life and breath, and everything else. And he has made of one blood all nations of people, to dwell over the face of the whole earth, having marked off the predetermined time periods and boundaries for their habitation, to seek after God, if perhaps they will grope for him and find him, though he is not far from each one of us. For in Him we live, and move, and have our being. As even one of your own prophets has said, ‘We are his offspring.’ We ourselves being offspring of God, we ought not therefore to think that the divine nature is anything like gold or silver or stone, like an engraved work of art and of human conception. Though God indeed forbore the times of such ignorance, he now commands all people of all places to repent.” Acts 17:24-30
“And I saw another angel flying at zenith, having an eternal gospel to herald above those dwelling on the earth, even over every nation and tribe and language and people, saying in a loud voice, ‘Fear God and give him glory; for the hour of his judgment has come; and worship him who created the heaven and the earth and the sea and the sources of waters.’ ” Revelation 14:6,7
While it is true that many humans like praise too much, or praise that is not deserved, or they are conceited, this is not true of God. His heart is pure.
"Great and marvelous are your deeds, O Lord God Almighty. Just and true are your ways, O king of the nations. Who shall not fear, O Lord, and glorify your name? Because you alone are pure.
O human being, you have a debt to God, to praise him. He is owed praise. Do not build up a praise deficit. This is the “Eternal Gospel” that an angel will have to announce as he flies over the whole planet.
