Here's what's so merry about Christmas...A baby was born who lived both a sinless and a righteous life, who although he did not deserve death, laid his life down as a sacrifice, and he claimed to do it for those who would believe on him. Then, after he had been dead for three days, His Father, who turns out to be God, raises Him from the dead confirming that He really did live a sinless and righteous life, that His sacrifice was effectual for those who would believe, and that everything that He taught while living on this Earth was true.
The merry Christmas we've been wanting is found here, not in a baby in a manger, or a baby receiving gifts from wise men, or even the young boy, Jesus, learning in the temple. Our merry Christmas is found when we see that Jesus had a reason for coming to this Earth, a mission to accomplish, which He accomplished with amazing totality.
