Oh that Christ-less sinners knew the fellowship of God-Whitefield

This is from a text sermon by George Whitefield on Abraham sacrificing Isaac.

"Behold, here I am. Being reconciled to God by the death and obedience of Christ, which he rejoiced in, and saw by faith afar off; he did not, like guilty Adam, seed the trees of the garden to hide himself from, but takes pleasure in conversing with God, and talketh with him, as a man talketh with his friend. "O that Christ-less sinners knew what it is to have fellowship with the Father and the Son! They would envy the happiness of saints, and count it all joy to be termed enthusiasts and fools for Christ's sake."

Declaring that man can be reconciled to fellowship with God is of course part of the Gospel proclaimation.
