This entire world is just one vast, dry desert, with the generations of men, lost travelers, following some will-o'-the-wisp or other - philosophical, psychological, philanthropic, political, educational, reformational, even religious suggestion-only to find them to be deluding mirages that rob them of what little hope self, sin and Satan may have left them. The rise of all sorts of cults, of off brand religions, of palm readers, of spiritualists, or clairvoyants, are but some of the signs of this thirst assailing mankind. No one has ever been able to find entire satisfaction for that burning longing save in the Lord Jesus Christ. May we then analyze His glorious invitation in this way. First, to what are we invited? Second, who is invited? Third, why should we accept the invitation?
