John Chrysostom (attributed)

In the very commencement he shews himself the messenger of a merciful Prince; he comes not with threats to the offender, but with offers of mercy. It is a custom with kings to proclaim a general pardon on the birth of a son, but first they send throughout their kingdom officers to exact severe fines. But God willing at the birth of His Son to give pardon of sins, first sends His officer proclaiming, Repent ye. O exaction which leaves none poor, but makes many rich! For even when we pay our just debt of righteousness we do God no service, but only gain our own salvation. Repentance cleanses the heart, enlightens the sense, and prepares the human soul for the reception of Christ, as he immediately adds, For the Kingdom of Hearen is at hand.
