Scripture refers to this fact about God directly in a number of places. For example, Jesus said, “I am the way, and the truth, and the life” (John 14:6), and He called the Holy Spirit “the Spirit of truth” (John 14:17; 15:26; 16:13). A more indirect affirmation that God is truth is Hebrews 6:18, which says that “it is impossible for God to lie.”
