Perseverance

Paul says in Philippians 1:6, “Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ.”  Now, there you have the doctrine of perseverance.   We persevere, not because we persevere, but because Christ is working in us.  Those who are truly saved may fall into sin, they may stray for a time, but they will endure, and they will stand until the day of his coming.
