There was a long silence. Throughout these concluding chapters of Isaiah, God has sounded the call to look only to him for strength and wisdom, help and hope, grace and guidance. This question implies no one has believed. The portrait of the Servant is an amazing one, especially since the nation of Israel was anticipating a coming, conquering king to restore the glory to the nation.
Life is all about people.
Life with others is about communication. Tell people faith. Faith people tell and people tell faith.
