The church of Christ, enfeebled, defective as she may appear, is the one object on earth upon which he bestows, in a special sense, his love and his regard. The church is the theater of his grace, in which he delights in making experiments of mercy on human hearts. The Holy Spirit is his representative, and it works to effect transformations so wonderful that angels look upon them with astonishment and joy. Heaven is full of rejoicing when the members of the human family are seen to be full of compassion for one another, loving one another as Christ has loved them. The church is God's fortress, his city of refuge, which he holds in a revolted world. Any betrayal of her sacred trust is treachery to him who has bought her with the precious blood of his only begotten Son. PH154 18.2
Christ speaks of the church over which Satan presides, as the synagogue of Satan. Its members are the children of disobedience. They are those who love to sin, and choose to sin, always laboring to make void the law of God, which is holy, just, and good. It is Satan's work to mingle evil with good, and to confuse the distinction between good and evil. Christ would have a church that labors to separate the evil from good, whose members will not knowingly tolerate wrong-doing, but will expel it from their own hearts and lives. How careful should we be in passing judgment on the work of others, how careful lest we become guilty of ascribing to evil agencies the manifestation of the Holy Spirit. PH154 19.1
