Into a world the is brutal, short, miserable.. afflicted with superstition, ignorance, disease, war, famine, tyranny. Welcome to Islam.. the ONLY other religion with a global messianic mission.. the heir apparent of the 'failed' Christian 'experiment'.
And if you'd ever read the Epistles, Cliffy.. you'd realize their is no contradiction between what Paul proclaimed and that which Mathew, Mark, Luke, John and the other revelators and apostles also did.
The entire moral and prophetic continuity of the Old and New Testaments forms a cohesive, integral, comprehensive, temporal whole. Ultimately it will be realized.. but it appears our pride and infidelity will drive us into a New Dark Age first.
