Others, however, understand this expression quite differently here and in the parallel texts. Eternal salvation is not something which we buy. Eternal salvation is unmerited. Nowhere in this passage is belief in Christ even mentioned. Second, those being addressed here are believers, not unbelievers.
Believers already have eternal salvation.
Rather, it is a rewards concept. There, nearly identical language is used and it clearly deals with possible rewards for people who are already eternally secure. Fourth, nowhere else in the Bible does the expression saving the psyche ever refer to eternal salvation from hell. It either refers to preserving one's physical life or to gaining eternal rewards. What the Lord actually meant by saving one's psyche here should be evident from the preceding four points.
