And your ears shall hear a word behind you, saying, This is the way, walk you in it, when you turn to the right hand, and when you turn to the left.
All Commentaries on Isaiah 30:21 Go To Isaiah 30
Gregory The Dialogist
AD 604
God opens the bosom of his loving kindness to us if we return to him after sinning, for he says by the prophet, “If a man puts away his wife, and she goes from him and marries another man, shall he return to her any more? Shall not that woman be polluted and defiled? But you have prostituted yourself to many lovers; nevertheless return to me, says the Lord.” Note how the plea of justice is proposed in regard to the wife who commits fornication and is deserted, and yet, for us who return after our fall, it is not justice but loving kindness that is shown. The inference is obvious, namely, that if our sins are spared with such great love, how great would be our wickedness if we sinned but failed to return after our sin, and what pardon can the wicked expect from him who does not cease to call them after they have sinned! This mercy of God in calling us after our sin is well expressed by the prophet, when it is said to him who turns away from him: “And your eyes shall see your teacher, and you ears shall hear the word of one admonishing you behind your back.”
