In these verses the “subjects of the Kingdom” may refer to unbelieving Jews who thought that their ancestry automatically entitled them entrance into the Kingdom of God. And because they were called God’s “chosen people” they truly believed that they were assured special favor by God. But there was no faith involved…and certainly no acceptance of Jesus Christ as their coming Messiah. Their puffed-up confidence and pride came only from their genealogy and lineage and was manifested in the taking on of a false religious appearance. They had put all their hope in being Children of Abraham, and “family” ties…not Children of God, and becoming part of the “family” of faith.
