Commentary on John 17:17

Sanctify them through thy truth: thy word is truth. Sanctify them - This word means to render pure, or to cleanse from sins, 1 Thessalonians 5:23 ; 1 Corinthians 6:11 . Sanctification in the heart of a Christian is progressive. It consists in his becoming more like God and less attached to the world; in his getting the ascendency over evil thoughts, and passions, and impure desires; and in his becoming more and more weaned from earthly objects, and attached to those things which are unseen and eternal. The word also means "to consecrate, to set apart to a holy office or purpose." See John 17:19 ; also the notes at John 10:36 .
