" A Christian must reject the philosophy of existentialism, but he must emphasize what is truly existential, for the Bible does not teach a static situation in which one becomes a Christian and that’s it. Rather, it teaches that time is moving, and a relationship to God is important at every given existential moment. Consequently, you do not begin the Christian life by faith and then remain static. You continue to live it by faith. Much of Paul’s teaching from Romans 5 on deals with this. The Christian, then, should be the true existentialist, moving upon the knife-edge of time, in every given moment being in relationship with God. Moment-by-moment living by faith "
