The parable ends with this final instruction to the servant: to do all that he can to make sure the master’s house is filled with guests. The servant represents all who belong to the true church, and who during this gospel age make it their business to gather as many as they can into the kingdom of heaven by communicating the gospel.
How many who call themselves Christians, are like these Jews. Their experience of religion is limited to externals, and they fool themselves into thinking that they love God and want to be with him. It is true that they do not want to perish in hell, but it is not true that they love spiritual things. When they catch a glimpse of the kingdom of heaven through the enlightenment of the Spirit, they draw back from something which seems foreign to them. They sense that they are being required to make a choice, and they stick with nominal religion which does not demand any great commitment from them, and certainly not the transformation of their whole being.
