Can a believer ever lose his salvation by sinning, ceasing to believe, or in any other way? There are various reasons that many Christians question their salvation. However, the doctrine of eternal security depends on what God has done, so that if salvation could be lost, then certain works of God would have to be reversed or undone. Scripture contains several central, meaty passages of Scripture to which our souls can anchor in seasons of doubt and that help us know with confidence that we are forever His.
