MeAm Lo'ez on Yeshayahu 41:1

Those who claim that the Jewish people cannot be redeemed, who are as far from G-d as the far-flung island dwellers, are called upon to "renew" their strength - to change their material strengths for spiritual ones, to abandon their religions of power and strength and accept the spiritual one - so that they be able to approach G-d in truth.  But first let them hear what G-d has to say before trying to argue with Him.
