A Sign for this Generation: Matthew 12:38-42

Not too long ago a bible teacher has declare that there would be a sign of God's wrath (The rapture) coming upon the world couple months ago. It'd reveal God's dislike. unfortunately, such prediction turn out to be void. As i reflect the path our world has taken with such an emphasis on scientific interpretation of our world. I could not avoid thinking on the sign Jesus himself say would be given to this generation. He say, "It'll be the sign of the prophet Jonah." Jonah was in the belly of a great fish for three long days, where God liberated him from to accomplish His will to preach to Nineveh, sort of the New York of our days. Many have alluded this historical event  as a story, myth, and went further to say, its a fable alluding it didn't really happen. However, according to Jesus, it did happen. The sign i think Jesus talks about is the "Gospel" and therefore the sign our generation will see is that of the gospel as well. The gospel implication isn't only a part salvivic, but it's embodied the wholeness of the person, be it his community, social, and environmental structure. In any case, this gospel is the death, burial, and resurrection of Christ Jesus and his outpouring of His Spirit on all flesh for the expansion of God's kingdom on earth. In the Synoptic gospels all the authors write about the same historical event. Our generation needs to see the sign of the gospel, beyond empirical hypothesis and theories of our world origin, they need to experience the gospel power. Our generation would only see God reveal, disclose and be interpreted through the gospel. There is no human devise, be it philosophical theories or mechanisms that can reveal the nature of God and person of God to our generation except through the gospel. Therefore, its imperative for us to galvanize  and make known the sign God has set in place even from the conception of the world, rap up in the bosom of Genesis 3. Meaning, purpose, love, power, and all freedom is found in nothing and no way else but in the Gospel of God, which is, the "Power of God unto Salvation".
