If Jesus was God how & why did he give power,riches,wisdom,strength,h... & blessing to himself ?

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."

You receive power, etc., from another, not from yourself !
Why or how could you give yourself something you already possess ?
