A Child Is Born is found in Isaiah 9:6-7. However, the first verse on down to the 13th concern the bondage to Assyria and the freedom brought by Gideon. The Jews exercised their pride and arrogance by leaving God out of rebuilding. Verses 6 & 7 describe not only the birth of the Messiah but jumps ahead to his coming reign forever.
"What Might Have Been" is based in Mark 11:1-11 on the entry of Christ into Jerusalem 483 years after Gabriel prophesied it in Daniel 9:25. The Jews were blind to the fact their Messiah arrived right on time for the fulfillment. Jesus wept over the city because of it.
