What is the work of the Holy Spirit? Jesus told His disciples: “When he, the Spirit of truth, is come, he will guide you into all truth” (John 16:13L). And the psalmist says: “Thy law is the truth.”(Psalm 119:142L) ... And since the law of God is “holy, and just, and good,”(Romans 7:12L) a transcript of the divine perfection, it follows that a character formed by obedience to that law will be holy.
