The trend of our lives tells us where we will be in the future. If that trend is backwards, trouble lies ahead. Backsliding must always be taken with utmost seriousness. While backsliding at any stage of growth must always be considered a present danger, we must on the other hand avoid becoming insecure. Our paranoia about security may keep us from doing anything constructive while we constantly check the state of our spiritual lives as if we expect to be falling from grace at any moment.
Entire sanctification does relate to security.
As we have seen, security is a relative thing - a person may be more secure or less secure. This likelihood of falling is dependent on us - on the decisions we make. A person living the sanctified life is one who has totally surrendered to the Lord as the Master of his or her life. Jesus is the Boss. This total consecration means that the individual has firmly set the pattern that all future decisions will be in accordance with the will of Jesus Christ.
