But this is that which giveth life unto the affections of believers; they know that in the enjoyment of God in Christ their eternal blessedness doth consist. How this is their happiness and glory, how it will give them an everlasting, overflowing satisfaction and rest, they understand in the first-fruits of it which they here receive. And this is the ultimate object of their affections in this world, and they go forth unto all other spiritual things in order hereunto. The more, therefore, their affections are fixed on them, the more they are kept up unto that due exercise, the nearer approaches they make unto this blessed state.

When their minds are possessed with this persuasion, when it is confirmed in them by daily experience of that sweetness, rest, and satisfaction, which they find in cleaving unto God with fervent love and delight, in vain shall any other objects rise up in competition to draw them off unto themselves. The more we love God, the more like we are unto him, and the more near the enjoyment of him.
