Merry Christmas! For the record, Latter-day Saints (Mormons) celebrate Christmas with Christians worldwide. We are grateful for the birth of Jesus Christ and the salvation that he brought and continues to bring because of his life and death.
On a different note, I find the teaching of Jesus recorded in John 14:12 absolutely fascinating.
Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father.
The question is how can those who believe in Jesus Christ do “greater works” than what he did? He raised the dead, gave sight to the blind, opened the ears of the deaf, walked on water, turned water into wine, etc.
The key, I believe, is in the last part of the verse–“because I go unto my Father.” If we continue to follow Christ and do his works even after we die, then we will do greater works than Jesus did in mortality because now he is doing even greater works than he did on earth.
This is another scripture that teaches the LDS concept of exaltation, I believe, although not on a superficial level.
