Does it say anywhere in the bible that God eats and drinks stuff? And sings?
Here's a short passage that comes to mind.
Mark 14
22 While they were eating, Jesus took bread, gave thanks and broke it, and gave it to his disciples, saying, “Take it; this is my body.”
23 Then he took the cup, gave thanks and offered it to them, and they all drank from it.
24 “This is my blood of the covenant, which is poured out for many,” he said to them.
25 “I tell you the truth, I will not drink again of the fruit of the vine until that day when I drink it anew in the kingdom of God.”
26 When they had sung a hymn, they went out to the Mount of Olives.
I'm fairly certain that the Lord did not eat and drink prior to His Incarnation. Since then, as the One with a dual nature, who has been and remains ~both~ fully God and fully Man since His Incarnation, I would think that food/drink would be important for Him. As you can see above, it appears that He not only ate/drank when He lived here among us, He will (or at least "can") continue to consume food/drink, now and in the future.
--David
p.s. - there's also this passage that describes one of His appearances AFTER His Resurrection, when He had His glorified, spiritual body (cf
1 Corinthians 15:44), the same body that He still has today.
Luke 24
36 While they were telling these things, He Himself stood in their midst and said to them, “Peace be to you.”
37 But they were startled and frightened and thought that they were seeing a spirit.
38 And He said to them, “Why are you troubled, and why do doubts arise in your hearts?
39 “See My hands and My feet, that it is I Myself; touch Me and see, for a spirit does not have flesh and bones as you see that I have.”
40 And when He had said this, He showed them His hands and His feet.
41 While they still could not believe it because of their joy and amazement, He said to them, “Have you anything here to eat?”
42 They gave Him a piece of a broiled fish;
43 and He took it and ate it before them.
