True sanctification, according to Scripture, comes through obedience to God's law—not through mystical experiences, spiritual exercises, or self-made devotions. While salvation is by grace through faith, sanctification is by the law, which guides believers in holy living. The church has often distorted this by either abandoning the law (under Greek influence or emotionalism) or confusing it with salvation (as in Pharisaism). Attempts at holiness apart from the law lead to legalism, asceticism, or spiritual pride. The biblical call to holiness—"Ye shall be holy: for I the Lord your God am holy" (Lev. 19:2)—is a command to obey God's law. The law is not optional or outdated; it is the rule of life and sanctification for individuals and institutions alike.
