There is no literature of any value on this subject. Simply put from the English Bible “faith is the substance (foundation) of things hoped for, the evidence of things unseen” and again “things seen are temporal things unseen are eternal”... The hope of faith is expectation as per the Greer texts “estin de pistos elpezOmenon = is yet faith expectation” Dead men speculate about “heaven” but unless one can see the Kingdom of heaven one cannot enter a house he cannot see. Messiah never said you would go to heaven he said “I am the life and the resurrection”. If the preachers amongst you know not this, then leave. After 40 years of reading Babylon's theology the central aspect of the Gospel is ignored in favour of faith for this life only. The translation the body of Messiah is the hope of the faithful in this Administration of Grace. As the beloved Apostle wrote, “we love His appearing” We ache for it as the thing unseen and our calling to Him, the substance of the things hope for and the evidence not seen.... those that have not this ache expect nothing an will indeed find it.
