No possibility of failure for the one who follows this plan

The apostle Peter had had a long experience in the things of God. His faith in God's power to save had strengthened with the years, until he had proved beyond question that there is no possibility of failure before the one who, advancing by faith, ascends round by round, ever upward and onward, to the topmost round of the ladder that reaches even to the portals of heaven.PCP 58.4
