Does doubting salvation make you unsaved?

When I was new in my faith in Jesus, someone worried that I wasn’t really converted because I was doubting my salvation. Can a person struggling with self-doubt have faith for salvation? Yes: The Bible doesn’t say that we are saved by confidence in ourselves, but by confidence in Jesus. Also, the Bible doesn’t say we have to suppress all anxieties, hide from all doubts and make ourselves feel good to know that we’re saved; a person might come up with all sorts of concerns, with fears feeding on fears. Rather, whatever else might be in our head, it is God’s Spirit, not our own doubtlessness, that assures us of salvation (Rom 8:16; 1 John 3:24).
