"The Word of the Lord came to Jonah" Jonah 1:1
God is faithful. God is faithful even when we are not. In the Book of Jonah we see God's faithfulness extended to everyone. To Jonah who was trying to run away from God. To the sailors who were able to hear about God. To the Ninevites who got their chance to repent. God was also faithful to His nature and His word, reaching out to all the characters in these events.
