"Having broken the chains by which it (the soul) was formerly bound, which all the empty anxieties of mortal life fastened round it, and having led it forth and emancipated it from them, he has stretched, and extended, and diffused it to such a degree that it reaches even the extreme boundaries of the universe, and is borne onwards to the beautiful and glorious sight of the uncreated God."—Philo, de ebrietate, 37.
So in Dr. Cudworth's sermon, which was printed some time ago:—
"When we have cashiered this self-will of ours, which did but shackle and confine our soules, our wills shall then become truly free, being widened and enlarged to the extent of God's own will."—Cudworth, Sermon before the House of Commons, p. 21.
"There is a straitnesse, slavery, and narrownesse in all sinne; sinne crowds and crumples up our souls, which, if they were freely spread abroad, would be as wide and large as the whole universe. No man is truly free but he that hath his will enlarged to the extent of God's own will, by loving whatsoever God loves, and nothing else.... He enjoys a boundlesse liberty and a boundlesse sweetnesse, according to his boundlesse love. He enclaspeth the whole world within his outstretched arms, his soul is as wide as the whole universe, as big as yesterday, to-day and for ever. Whosoever is once acquainted with this disposition of spirit, he never desires anything else; and he loves the 'life of God' in himself, dearer than his own life."—Id., p. 56.
And finally in the Imitatio Christi:—
"They that willingly and freely serve Me shall receive grace for grace. But he who desires to glory in things out of Me, or to take pleasure in some private good, shall not be grounded in true joy, nor be enlarged in his heart, but shall many ways be encumbered and straitened.... And if heavenly grace enter in and true charity, there will be no envy nor narrowness of heart, neither will self-love busy itself. For Divine charity overcometh all things and enlargeth all the powers of the soul."—De Imitatione Christi, iii. 9.
We conclude, then, that self can never measure the length and breadth of the Divine love, and run in the way of His commandment. We need God to make us understand God; we must be in union with Him in order to obey Him. Distances on the earth may be measured by a foot-rule or a surveyor's chain, but to measure the spaces between the stars we must have a base-line in the sky. Only by being partakers of the Divine nature can we live out the Divine life; and no man knoweth the Father save the Son, and He to whom the Son will reveal Him.
