Sanctify them through thy truth: thy word is truth.
John 17:17 (KJV)
To be sanctified means to be set apart for God’s purposes in our life. We are sanctified through the Word because the more that we allow the Word of God to fill our hearts and minds, the more will our thinking and our words reflect the purposes of God. This is when we find that God’s purposes for us are to have victory and good success in every area of life.
