"To be born again is, as it were, to enter upon a new existence, to have a new mind and a new heart, new views, new principles, new tastes, new affections, new likings and new dislikings, new fears, new joys, new sorrows, new love to things once hated, new hatred to things once loved, new thoughts of God and ourselves and the world and the life to come, and the means whereby that life is attained. And it is indeed a true saying that he who has gone through it is a new man, a new creature, for old things are passed away—behold, he can say, all things are become new! It is not so much that our natural powers and faculties are taken away and destroyed; I would rather say that they receive an utterly new bias and direction. It is not that the old metal is cast aside—but it is melted down and refined and remolded, and has a new stamp impressed upon it, and thus, so to speak, becomes a new coin.
To be born again is to become a member of a new family by adoption, even the family of God; it is to feel that God is indeed our Father, and that we are made the very sons and daughters of the Almighty; it is to become the citizen of a new state, to cast aside the bondage of Satan and live as free men in the glorious liberty of Christ's kingdom, giving our King the tribute of our best affection, and believing that He will keep us from all evil. To be born again is a spiritual resurrection, a faint likeness indeed of the great change at last—but still a likeness; for the new birth of a man is a passage from death to life; it is a passage from ignorance of God to a full knowledge of Him, from slavish fear to childlike love, from sleepy carelessness about Him to fervent desire to please Him, from lazy indifference about salvation to burning, earnest zeal; it is a passage from strangeness towards God to heartfelt confidence, from a state of enmity to a state of peace, from worldliness to holiness, from an earthly, sensual, man-pleasing state of mind to the single-eyed mind that is in Christ Jesus. And this it is to be born of the Spirit."
