Are You Trusting In Your Own Ability to Persevere?
Those who think they can lose their salvation are not trusting in Jesus Christ alone for salvation but partly trusting in their own righteousness. Such teaching would have you believe that the sacrifice of Jesus was insufficient to make his people perfect forever (Heb 10:14) or save them to the uttermost (Heb 7:25) [i.e. that Jesus is not enough]. ... such that, in addition to what Christ did, they must join their own ability to persevere in order to maintain their own just standing before God. The book of Hebrews and Galatians severely warns against this and all teaching that rejects the sufficiency of Christ alone (Heb 6 & 10; Gal 3:3).
