Commentaries:
This passage makes it very plain that God in composition is spirit, that He does have form, that He is solid, and He has skin and bones. The description even includes scars in His hands and feet!

The Holy Spirit and the Trinity (Part 1)
Consider the context and the time. He is resurrected, composed of Spirit. He is God. Does He indicate at all that being in the body is only a part-time experience for God? No, instead He teaches them that a spirit being's body is not vaporous like a ghost and that it is not composed of earthly flesh and bone.
The implications are important in relation to other parts of the Bible. In this case, what He does not say is important because He wants them to answer in their own minds just the opposite of what they originally thought, "This is a ghost. It has no form or shape."
Yes, He did have form and shape, and it was solid to the touch. They felt Him, and their hands did not pass through Him. He is saying that He has flesh and bones, but they are not physical. They are spirit flesh and bones.
