+I. Ungodly men have fears concerning the future.+ These fears proceed from a consciousness of past sin and present guilt, and prove the existence within man of a moral standard of action. In the natural world, we know that certain effects invariably follow certain causes. Sunlight and genial rain produce fertility and beauty, the hurricane and the flood leave behind them desolation. There are certain particles whose action, if diffused abroad in the air, breed disease and death; there are others whose effects are most refreshing and healthful to the body frame. Coming into the region of human action and moral responsibility, there are certain actions of men which clothe the spirit with gladness, making the soul as a field which the Lord God hath blest, and there are acts which leave behind them a sting which brings utter desolation. There are deeds done by moral agents which are followed by the disapprobation of conscience in proportion as conscience is educated by moral light, and there are those which are well-springs of joy in the human heart. It is to conscience that we must refer the fears of the wicked in relation to the future. +II. The certainty that the fears of the wicked will be realised.+ 1. _From the inequality of rewards and punishments in the present._ There are men whose characters seem to be almost perfect who have not the reward at present which their integrity and uprightness deserve. There are many men who sit, as it were, like Lazarus, at a rich man's gate in poverty, who are much better men than the rich man himself. The difference in the character of the man who passed the sentence of death upon Paul, and Paul himself calls for a more manifest impartiality on the part of the Divine Ruler in the eternity to come. We feel certain that elsewhere a just sentence has been passed upon Paul and Nero. The inequality in the present dealings of God with the righteous and the wicked demands that in the future the "fear of the wicked shall come upon him." 2. _From the admonition of conscience._ Although the mariner's compass is sometimes unsteady, its direction is always towards the north. And the human conscience, however it may occasionally waver, points to a future judgment. It is not an _occasional_ occurrence but so _universal_ as to be a prophecy of a fact. 3. _From the necessity that God should fulfil His own appointment._ Revelation declares that, "He hath appointed a day, in which he will judge the world in righteousness by that man whom He hath ordained" (Acts xvii. 31). The Righteous Judge of all the earth must keep His own appointment, therefore every wicked man must have what he does not desire, viz., a fair and impartial trial.
