Does God's word speak of judgment on a nation whose people disobey his word, as in abortion, where it has been made legal but is contrary to God's Word to murder?
The Bible provides examples of nations that experienced God’s judgment for their godlessness. The worldwide flood in Noah’s day comes to mind first; all nations were destroyed. Other examples include the northern tribes of Israel, and all the nations in Isaiah 10 – 34 that faced God’s judgment.
The Bible makes it clear that “Righteousness exalts a nation, but sin condemns any people” (Proverbs 14:34). Also, “Blessed is the nation whose God is the LORD, the people he chose for his inheritance” (Psalm 33:12). Psalm 2 offers an interesting picture of the relationship between God and the nations of the world and their rulers.
All this is reason why, in the context of your question, it is important for us to offer a prayer like this: “Almighty and eternal God, who created this world and all of us in it, we thank you for the blessing of our life. And we thank You that You created us wonderfully. Lead all people everywhere to see Your work in the creation of life and to consider human life as sacred. Help us to stop the wanton destruction of newly created life in the mother’s womb. Protect and defend all to whom you give life until that day when you take their life from them again. Lead people everywhere to see the sin of abortion and all other sins and to recognize that they are under your wrath and punishment because of them. And then bring them to the precious knowledge of Your Son Jesus, so that they may have eternal life in His name. We ask this so that Your will may be done on this earth and that Your kingdom may come to all people. Amen.”
