Two Deadly Ways to Overcome This Fear
There are two opposite ways to ruin your life in trying to overcome this fear. One is to assume that perseverance in faith and love is not necessary for final salvation. And the other is to assume that perseverance is necessary and then depend on our efforts in some measure to fulfill that necessity and to secure God’s favor. Let me show why both these are devastatingly misguided and deadly, and then what is the biblical way of finishing life to the glory of Christ.
Deadly: “Perseverance Is Unnecessary”
It’s a mistake to think that perseverance in faith and love is not necessary for final salvation. A deadly mistake. Jesus said in Mark 13:13, “You will be hated by all for my name’s sake. But the one who endures to the end will be saved.” Hebrews 12:14 says, “Strive for peace with everyone, and for the holiness without which no one will see the Lord.”
In Galatians 6:8–9, Paul says, “The one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life.” So notice that the two reapings are of corruption on the one hand and eternal life on the other hand. Then he says in the next verse, “And let us not grow weary of doing good, for in due season we will reap [eternal life], if we do not give up.”
So clearly persevering in the furrows of faith by sowing to the Spirit and bearing his fruit of love is necessary for final salvation. “God chose you,” Paul says in 2 Thessalonians 2:13, “. . . to be saved, through sanctification by the Spirit and belief in the truth.” “Saved through sanctification” means that sanctification—the path of love—is the path on which saved sinners go to heaven. And it’s the only path that leads to heaven.
So it is a tragic and deadly mistake to try to overcome the fear of not persevering in old age by saying you don’t have to persevere.
Deadly: “Perseverance Puts or Keeps God on Our Side”
But the other misguided way of overcoming the fear of not persevering is just as dangerous. It is the way that says: “Yes, perseverance in faith and love is necessary, and that means I must wait till the last day for God to be 100% for me, and I must depend on my efforts to secure God’s full favor. God may get me started in the Christian life by faith in him alone, but perseverance happens another way. God makes his ongoing favor depend on my efforts.” That, I say, is deadly and leads either to despair or pride. And certainly not to perseverance.
