If we could condense all the truths of Christmas into only three words, these would be the words: 'God with us.'
Bethlehem was God with us, Calvary was God for us, and Pentecost is God in us.
The best of all is God with us
If we are given gold, would we not test it to determine it's value? If we doubted its genuineness - we would test it by fire...and so God with us.
