q. 8.-" What is the difference between 'Sanctify them through Thy truth' (Jno. 17:17) and 'Sanctified in Christ Jesus' (1 Cor. 1:2)?"
Ans.-In the order of blessing, the passage in Corinthians comes first. It is a blessed fact that in Christ all our blessings are perfect. Attainment is not in question. All in Christ are sanctified, perfectly set apart to God, separated unto Him and for Him. This sanctification is perfect, it is the work of a moment, the portion of every believer. Hence our name, "saints." This is the position of all believers; but the passage in Jno. 17:is different. Our Lord is leaving His own in the world; His great desire is that they may be kept from evil, left here to represent Him. To do this, they must be holy. Hence the prayer, "Sanctify them through Thy truth." The practical walk is in question, and here sanctification is a gradual and progressive work. As the Word of God enters the heart, it shows us our unlikeness to Christ, then (by occupying us with Him,) fashions us into His image through the Spirit.
Q. 9.-"Does God own the gospel, or His Word, when preached by an unbeliever-1:e., an unredeemed person ?"
Ans.-Phil. 1:18 seems to give the answer clearly. It is His Word which God uses; and solemn as the handling of that Word by an unsaved person is, He may in His sovereign grace use it. So we can rejoice where Christ is preached, though the judgment on those who preach not sincerely will be sure.
