From Oswald Chambers: "My Most for His Highest"
"We pray to be sanctified, are we prepared to face the standard of these verses (1 Thessalonians 5:23-24)? We take the term sanctification much too lightly. Are we prepared for what sanctification will cost? It will cost an intense narrowing of all our interests on earth, and an immense broadening of all our interests in God. Sanctification means intense concentration on God's point of view. It means every power of body, soul and spirit chained and kept for God's purpose only. Are we prepared for God to do in us all that he separated us for? And then after his work is done in this, are we prepared to separate ourselves to God even as Jesus did? "For their sakes I sanctify myself." The reason some of us have not entered into the experience of sanctification is that we have not realized the meaning of sanctification from God's standpoint. Sanctification means being made one with Jesus so that the disposition that ruled him will rule us. Are we prepared for what that will cost? It will cost everything that is not of God in us.
"Are we prepared to be caught up into the swing of this prayer of the apostle Paul's? Are we prepared to say -"Lord, make me as holy as you can make a sinner saved by grace"? Jesus has prayed that we might be one with him as he is one with the Father. The one and only characteristic of the Holy Ghost in a man is a strong family likeness to Jesus Christ, and freedom from everything that is unlike him. Are we prepared to set ourselves apart for the Holy Spirit's ministrations in us?"
