Many angels worship
Rev 5:11 And I beheld, and I heard the voice of many angels round about the throne and the beasts and the elders: and the number of them was ten thousand times ten thousand, and thousands of thousands;
More angels than can be counted: One hundred million angels and thousands of thousands. This was not in a small room, Can God be contained?
Rev 5:12 Saying with a loud voice, Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing.
Worthy is the Lamb who was slain, there is no doubt that the Lamb is every bit God, the Son of God.
Rev 5:13 And every creature which is in heaven, and on the earth, and under the earth, and such as are in the sea, and all that are in them, heard I saying, Blessing, and honour, and glory, and power, be unto him that sitteth upon the throne, and unto the Lamb for ever and ever.
All creation worship God the Father and God the Son.
Phil 2:8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
Phil 2:9 Wherefore God also hath highly exalted him, and given him a name which is above every name:
Phil 2:10 That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;
Phil 2:11 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
Rev 5:14 And the four beasts said, Amen. And the four and twenty elders fell down and worshipped him that liveth for ever and ever.
"Depend upon it, my hearer, you never will go to heaven unless you are prepared to worship Jesus Christ as God. They are all doing it there: you will have to come to it, and if you entertain the notion that he is a mere man, or that he is anything less than God, I am afraid you will have to begin at the beginning and learn what true religion means. You have a poor foundation to rest upon. I could not trust my soul with a mere man, or believe in an atonement made by a mere man: I must see God himself putting his hand to so gigantic a work."
