At present, we are working with the light of truth presented by Dr. Francis Schaeffer from his book True Spirituality.
So…as the only basis for the removal of our guilt is the finished work of Christ upon the cross in history, plus nothing, so the only instrument for accepting that finished work of Christ upon the cross is faith. This is not faith in the twentieth-century or Kierkegaardian concept of faith as a jump in the dark—not a solution on the basis of faith in faith. It is believing the specific promises of God; no longer turning our backs on them, no longer calling God a liar, but raising the empty hands of faith and accepting that finished work of Christ as it was fulfilled in history upon the cross. The Bible says that at that moment we pass from death to life, from the kingdom of darkness to the kingdom of God’s dear Son. We become, individually, children of God. We are children of God from that time on. I repeat, there is no way to begin the Christian life except through the door of spiritual birth, any more than there is any other way to begin physical life except through the door of physical birth.
Yet, having said this about the beginning of the Christian life, we must also realize that while the new birth is necessary as the beginning, it is only the beginning. We must not think that because we have accepted Christ as Savior and are therefore Christians, this is all there is in the Christian life. In one-way physical birth is the most important part in our physical life, because we are not alive in the external world until we have been born. In another way, however, it is the least important of all the aspects of our life, because it is only the beginning and then it is past. After we are born, the important thing is the living of our life in all its relationships, possibilities, and capabilities. It is exactly the same with the new birth. In one way, the new birth is the most important thing in our spiritual life, because we are not Christians until we have come this way. In another way, however, after one has become a Christian, it must be minimized, in that we should not always have our mind only on our new birth. The important thing after being born spiritually is to live. There is a new birth, and then there is the Christian life to be lived. This is the area of sanctification, from the time of the new birth through this present life, until Jesus comes or until we die.
