In preparation for the sermon Sunday Evening I ran across this excellent statement by Charles Spurgeon:
He [Paul] was persuaded that heaven could not be heaven if Christ was not there. Oh, to think of heaven without Christ! It is the same thing as thinking of hell. Heaven without Christ! It is day without the sun; existing without life, feasting without food, seeing without light. It involves a contradiction in terms. Heaven without Christ! Absurd. It is the sea without water, the earth without its fields, the heavens without their stars. There cannot be heaven without Christ. He is the sum total of bliss; the fountain from which heaven flows, the element of which heaven is composed. Christ is heaven and heaven is Christ.
