1. Come, for everything is ready (15-20)
One of the guests was reminded of the great heavenly banquet of the Messiah (15). So Jesus told a parable about the kingdom of God. What a tragedy it was that God's chosen people were too busy with private, worldly affairs to come to the great Messianic banquet which God prepared for them. Christians who neglect prayer and Bible study, or who put their own business ahead of God's, can become like this, too.
2. Those from the streets and roads (21-24)
When the Jews rejected God's Messiah, God opened the door to the Gentile world. All who need his mercy--the poor, the crippled, the lame and the blind and all sinners--are invited to come. His grace is free. It is offered to those who cannot repay him. The guests at the great banquet in the kingdom of heaven will be those who accept his love and come to him by faith.
