Isaiah 45 is a message of hope for the world, but it is a hope realized only by those who trust in God. If we believe and confess that God is the Creator of the heavens and earth, that he has spoken his plans and foretold the future, that God speaks the truth and accomplishes his promises, and that there is no other righteous God and Savior for humanity, then it is possible to turn to God and be saved. It doesn’t matter who that person is, where that person is from, what their background is, or what they have thought or done in the past. A righteous God makes his salvation open to all.
