Again, we must emphasize that entering into obedience, thus attaining this security, does not mean that we can never fall (as the doctrine of "eternal security" or "perseverance of saints" suggests). Peter reminds us that it is possible to attain the "knowledge of the Lord" but to "turn from the commandment" of God (2 Peter 2:20-22). Jude also warns us to "guard" ourselves: "Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life" (Judges 1:21).
