The sign of the prophet Jonah is only one of approximately 350 prophecies fulfilled by Jesus Christ that were recorded up to 4000 years before he was born. Prophecies act as signs and proof of the credibility of God and of his ability to save people from certain death. The salvation message that Jesus made possible, is also built upon prophetic signs, miracles, and wonders. The sign of speaking in tongues is the confirmation of being anointed by the Spirit. The sign of the prophet Jonah is a precursor of the salvation message that Jesus provided and described.
