The Perseverance of the Saints
The doctrine of the perseverance of the saints is not some old stuffy theological ethereal doctrine given to us from a an ivy tower by some stodgy theologian. No, it is the engine, the fuel, that fires the Christian up and helps him to run on all cylinders.
Just what does it mean to persevere? Actually it is part of our sanctification---we as God's people have been declared holy (Eph. 1:4). In short, the word holy means to be set apart, sacred, used by God for his purposes. So, to persevere is to be kept by the power of God, through the faith that He has given His people.
When the believer realizes that his salvation is of the Lord---he can live with confidence that God will keep him until he reaches heaven (1 Peter. 1:3-5). We will persevere and therefore we are secure, because we will persevere.
Christian live each day in the reality that it is God, the creator, king, and supreme ruler of heaven and earth who has committed Himself to keep each and everyone who are in His family.
