The principal end of man's creation to which Scripture points, is that, made in the likeness of God, he was to live with God forever. And here on earth he should praise God, thank Him, and obey His Word in patience. This end we do attain to some extent in this life, although in weakness; but in the future life we shall achieve it to perfection.
