The moment we accepted Jesus Christ as our Savior, we were justified and our guilt was gone once for all. That is absolute. But if we want to know anything of relaity in the Christian life, anything of true spirituality, we must “take up our cross daily.” The principle of saying no to self lies at the heart of my attitude toward the world as it maintains its alien stand in bebellion aginst he Creator. If I use my intellectual capacities to make myself respectable to the world, as it is in revolution against the one who created it, then I have failed. It is equally true if I use my ignorance for the same purpose. I am to face the cross of Christ in every part of life and with my whole man. The cross of Christ is to be a reality to me not only once for all at my conversion, but all through my life as a Christian.
