It should be a given for Christians, that due to the fall, all human beings are not safe from temporal and eternal punishment. Why should it, therefore, so surprise Olson that God justly exercises this authority during our lives? Judgement has already begun east of Eden and we all are subject to death. So nothing (no suffering) should surprise us here except for the great mercy He has shown us in Jesus Christ. Regarding the Tower of Siloam (Luke 13:4), Jesus declared that it did not fall on people for their particular sin(s) because they were somehow worse that others, but as a sign in this fallen world that we are all ill-deserving sinners, under a curse who need to repent and receive the mercy of Jesus Christ. Don't be surprised that the tower fell on those people - let it be a sober reminder that you deserve the same.
