John Wesley emphasizes that faith does not nullify the law but rather establishes it, urging believers to preach the law in its entirety and to live in accordance with it. He warns against the common misconceptions that faith diminishes the necessity of holiness or that it allows for sin under the guise of grace. Wesley asserts that true faith leads to a life of holiness, love, and obedience to God's commandments, which are essential for a genuine Christian life. He encourages believers to establish the law in their hearts and lives, recognizing that faith is a means to restore the law of love that God intended from the beginning. Ultimately, Wesley calls for a faith that produces love and holiness, fulfilling the law in both spirit and action.
