We have to be fair here in that Heaven is such a mystery it’s hard to say how we will fully perceive things. Yes, Jesus did show the holes in His hands to Thomas, but when we see Him in a Heavenly dwelling perhaps we will be able to comprehend Him. However, now I think it would be impossible, I can’t imagine what this truly looked like to John:
Rev 5:6 And between the throne and the four living creatures and among the elders I saw a Lamb standing, as though it had been slain, with seven horns and with seven eyes, which are the seven spirits of God sent out into all the earth.
19:13 He is clothed in a robe dipped in { Some manuscripts b sprinkled with b } blood, and the name by which he is called is The Word of God.
Of course Revelation is filled with this sort of symbolism but it only shows that we can’t be entirely sure what Heaven will look like to us. Likely we’ll be able to comprehend what we see, but unlikely would we be able to put it into words here on Earth. John did his best.
