What does the Bible say about assurance for all men?

In Acts 17:31, the apostle Paul proclaims that God has appointed a day of judgment and has assured all men of this through the resurrection of Christ. This assurance serves a dual purpose: for the unbeliever, it highlights the certainty of divine judgment; for the believer, it offers comfort through the acknowledgment that Christ has taken on judgment on their behalf. Thus, the resurrection is the ultimate assurance of God’s justice and mercy, encapsulating the idea that those who trust in Christ are not condemned but are assured of life eternal.
