Only - That is, This is “all” that will occur to you. The only thing which you have to anticipate is, that you will see how God punishes sinners.
With thine eyes shalt thou behold and see the reward of the wicked - Your own eyes shall see it. See the notes at Psalms 37:34. You will see the just punishment of the ungodly, the vicious, the profane, the sensual. You will see what is the proper fruit of their conduct; what is the just expression of the views which God takes of their character. This undoubtedly refers to the general principle that there is a moral government on earth; that vice is often punished as such; that the general course of the divine dealings is such as to show that God is favorable to virtue, and is opposed to vice. The system is not complete here, and there are many things which could not be reconciled with this, if the present world were all, and if there were no future state: but the course of events indicates the general character of the divine administration, and what is the tendency of things. The completion - the actual and perfect adjustment - is reserved for a future state. The facts as they occur on earth prove that there is an attribute of justice in God; the fact that his dealings here are not wholly and fully in accordance with what justice demands, proves that there will be a state where full justice will be done, and where the whole system will be adjusted.
