In our church it is a very common theme, but I agree with you that on an overall basis it is not preached much.
But then again, it doesn't seem that preaching about Jesus coming again gets very much attention either.
One of the most remarkable scriptures to me is found in
Revelations 1:14-16:
14 His head and his hairs were white like wool, as white as snow; and his
eyes were as a flame of fire;
15 And his feet like unto fine brass, as if they burned in a furnace; and his voice as the sound of many waters.
16 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 strength. (KJV)
What amazes me about this passage is the areas I have emphasized. His countenance was as looking at the sun in it's strength and yet in the midst of that brilliance John describes His eyes as a flame of fire.
Can you imagine point out a fire in the midst of the sun? The brilliance and Majesty of the One we call King is an amazing thing.
