3Let the people praise thee, O God; let all the people praise thee.
4O let the nations be glad and sing for joy: for thou shalt judge the people righteously, and govern the nations upon earth. Selah.
How would you describe a perfect government? Many things come to mind, but perhaps the most critical attribute of a perfect government would be a perfect judicial system. We have a lot of fun at lawyers' expense, but our jokes sadly express our low expectations for lawyers. We do not even expect an honest judiciary.
God judges the nations righteously. We do not often think about the consequences that nations will pay for their ungodly actions; even as Christians, we seem to forget that God does hold the nations in account for their actions. In response to their actions, He allows some nations to rise and others to fall.
In the Old Testament we have many examples of God allowing nations to successfully war against Israel and Judah, and then we see God's judgment brought upon those very nations for their atrocities against His people. God does not overlook one thing; all nations will be held in account for their actions.
In this self sufficient world, we often forget that God has a plan for this world--a plan which is being carried out perfectly. Nothing in this world happens apart from God's knowledge, and nothing that man can do will stay the hand of God.
From the beginning Satan has determined to upset God's plan, but his efforts have all been overridden by God. Satan tempted Adam and Eve in the Garden of Eden, hoping to destroy the entire human race, but God already had a plan of redemption in place.
As Christians we can indeed say,
O let the nations be glad and sing for joy: for thou shalt judge the people righteously, and govern the nations upon earth.
Though while on this earth we only see through a glass darkly, we can be assured that God's Word is true; everything He has ordained will come to pass. God does, indeed, judge the nations, and He will judge righteously. We are on the victorious side; God rules both now, and forever more!
God Bless You,
