Sanctify them through thy truth: thy word is truth (John 17:17).
Whatever God has said about you in His Word is the reality; that’s the truth about you. For example, the Word says, “...Greater is He that is in you than he that is in the world” (1 John 4:4). That means you can’t be oppressed; you can’t be defeated or disadvantaged in life, because the greater One, with all His wisdom, power, and glory, lives in you. Another truth is in 1 John 3:2 that says, “Beloved, now are we the sons of God….” You’re a child of God now; not next year or when you get to heaven; it’s a present-hour truth. You’re born of Him, and that makes you an associate of the God-kind.
