What does the Bible say about how can I know I'm saved?

The Bible teaches that assurance of salvation comes solely through faith in Jesus Christ, not our own works or righteousness. The question 'How can I know?' reflects the human tendency to seek assurance in our performance rather than in the finished work of Christ. Genesis 15 illustrates this as God reassures Abraham after he questions His promise. Believers are reminded that if they look to themselves for assurance, they miss the essence of the Gospel, which centers on Christ as our hope and righteousness.
