Perseverance

The perseverance of the saints is the doctrine that those whom God has genuinely regenerated will persevere in faith and holiness to the end and will ultimately be saved — not because of their own unaided strength but because God faithfully preserves them by his Spirit. It is one of the five points of Calvinism (the "P" of TULIP) and is closely connected to the doctrines of election and effectual calling. The biblical basis rests on divine preservation texts: "My sheep hear my voice... and I give them eternal life, and they will never perish, and no one will snatch them out of my hand" (John 10:27–28); "He who began a good work in you will bring it to completion at the day of Jesus Christ" (Phil. 1:6); "I am sure that neither death nor life... will be able to separate us from the love of God" (Rom. 8:38–39). Perseverance does not mean that true believers never sin, experience doubt, or temporarily wander, but that they will ultimately return and not finally apostatize. Arminian theology holds instead to conditional security — believers can forfeit salvation by apostasy. The warning passages in Hebrews (6:4–6; 10:26–31) are interpreted differently by the two traditions: either as warnings to those who were never truly regenerated, or as genuine warnings to true believers who can fall away.
