We Christians must simplify our lives or lose untold treasures on earth and in eternity. Modern civilization is so complex as to make the devotional life all but impossible. The need for solitude and quietness was never greater than it is today.
Christian theology teaches the doctrine of prevenient grace, which briefly stated means this, that before a man can seek God, God must first have sought the man.
No one can know truth except the one who obeys truth. You think you know truth. People memorize the Scriptures by the yard, but that is not a guarantee of knowing the truth. Truth is not a text. Truth is in the text, but it takes the text plus the Holy Spirit to bring truth to a human soul.
Holiness, as taught in the Scriptures, is not based upon knowledge on our part. Rather, it is based upon the resurrected Christ in-dwelling us and changing us into His likeness.
