I think we must remember God who has no form is not a man as us, never was never will be.
Another form was in respect to the spirit of holiness, by the resurrection. It was a vision as a theophany prior to the later actual demonstration using sinful flesh needed to put away sin in the flesh. The spirit of holiness (not seen) is not recognized by His birth.
Romans 1:4 And declared to be the Son of God with power, according to the spirit of holiness, by the resurrection from the dead:
We can see it I believe in the parable below.
And was transfigured before them: and his face did shine as the sun, and his raiment was white as the light.And, behold, there appeared unto them Moses and Elias talking with him.Mat 17:2
And I turned to see the voice that spake with me. And being turned, I saw seven golden candlesticks;And in the midst of the seven candlesticks one like unto the Son of man, clothed with a garment down to the foot, and girt about the paps with a golden girdle.His head and his hairs were white like wool, as white as snow; and his eyes were as a flame of fire;And his feet like unto fine brass, as if they burned in a furnace; and his voice as the sound of many waters. And he had in his right hand seven stars: and out of his mouth went a sharp twoedged sword: and his countenance was as the sun shineth in his strengtRev 1:12
