What does the Bible say about the end times and judgment?

Scripture consistently teaches that there is a day of reckoning approaching, where all people will be judged based on their response to God. Malachi 3:2-3 poses the question of who can endure the day of the Lord's coming, emphasizing His purifying judgment. For the believer, this is a day of assurance as they stand in Christ's righteousness; for the unrepentant, it is a day of condemnation. This doctrine serves to remind believers of the importance of living in light of Christ's return, standing firm in faith, and sharing the gospel with others. It reflects God's holiness and justice while demonstrating His mercy in salvation offered through Jesus.
