What does it mean that God will not clear the guilty?

The phrase that God will not clear the guilty emphasizes His righteous character in dealing with sin. In Mark 15:34, when Jesus cries out, 'My God, my God, why hast thou forsaken me?', it reflects the seriousness of sin and the necessity of atonement. God’s justice demands that sins be punished, and this is precisely why Christ’s sacrifice was necessary. He bore the guilt of His people, satisfying divine justice so that they may be forgiven. Thus, Jesus’ resurrection signifies that God's justice has been perfectly satisfied, allowing believers to receive peace.
