Chapter 55 A Call To Respond To The Witness of the Servant And The Certainty Of Its Success.
God (or the Servant) now sends out a call to Israel and the nations to respond to what is on offer through the Servant. They must come and eat and drink, and enjoy the portion that He has obtained (Isaiah 53:12) and offers to share with all. It is guaranteed by an everlasting covenant (Isaiah 55:3), and in the presentation of the work and splendour of the Servant through Whom it is obtained (Isaiah 55:4-5). And its success is guaranteed (Isaiah 55:5). Let men then seek Yahweh, turning from sin and coming to Him (Isaiah 55:6-7), and they will find mercy and abundant pardon.
And in the end the success of what He has done will not depend on man. His word will go out and be effective and fulfil all His will because of its intrinsic power as His word (Isaiah 55:9-13) revealing the everlasting greatness of Yahweh (Isaiah 55:13).
