"In 1Tim.1:1, Paul calls "Christ our hope." 
Of course a true gospel hope must center in Jesus Christ as the object, being, or agency, through whom the promises of God concerning man are to be carried out.
He is the Alpha and Omega.
Alpha being the first Greek letter, and Omega, the last one...in other words, the whole alphabet.
So Christ is the Alpha and Omega, or the alphabet of God's plan and purposes concerning man." J.N. Louborough
