The one true Church is composed of all believers in the Lord Jesus. It is made up of all God's elect - of all converted men and women - of all true Christians. In whomever we can discern the election of God the Father, the sprinkling of the blood of God the Son, the sanctifying work of God the Spirit, in that person we see a member of Christ's true church.
I doubt, indeed, whether we have any warrant for saying that a man can possibly be converted without being consecrated to God. More consecrated he doubtless can be, and will be as his grace increases; but if he was not consecrated to God in the very day that he was converted and born again, I do not know what conversion means.
To be born again is, as it were, to enter upon a new existence, to have a new mind, a new heart, new views, new principles, new tastes, new affections, new likings, 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 salvation.
There are very few errors and false doctrines of which the beginning may not be traced up to unsound views about the corruption of human nature. Wrong views of the disease will always bring with them wrong views of the remedy. Wrong views of the corruption of human nature will always carry with them wrong views of the grand antidote and cure of that corruption.
Doctrine is useless if it is not accompanied by a holy life. It is worse than useless; it does positive harm. Something of 'the image of Christ' must be seen and observed by others in our private life, and habits, and character, and doings.
Inability to distinguish doctrine is spreading far and wide, and so long as the preacher is "clever" and "earnest," hundreds seem to think it must be all right, and call you dreadfully "narrow and uncharitable" if you hint that he is unsound!
Faith is to the soul what life is to the body. Prayer is to faith what breath is to the body. How a person can live and not breathe is past my comprehension, and how a person can believe and not pray is past my comprehension too.
