“For the horses of Pharaoh with his chariots and his horsemen went into the sea, and the Lord brought back the waters of the sea on them, but the sons of Israel walked on dry land through the midst of the sea” (Exodus 15:19, NASB).
You might notice in this verse from the Song of Moses, which proclaims God’s greatness in helping Israel escape from Egypt, that the same miracle that God used to deliver the Israelites is also the same miracle that God used to destroy Pharaoh’s army!
“And what if God, desiring to display His wrath and to make His power known, endured with much patience objects of wrath ready for destruction. And what if He did this to make known the riches of His glory on objects of mercy, that he prepared beforehand for glory–on us, the ones He also called, not only from the Jews but also from the Gentiles?” (Romans 9:22-24, HCSB).
These verses do not mean that God desires to show His wrath on those who deserve it. Rather, they mean that God desires to show His mercy by saving those who deserve His wrath. And, God can best show His love by having mercy on those who deserve His wrath.
“Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him.” You’ve probably seen these “how to do” books that focus on some subject or skill and the target audience purports to be “dummies” or those who are not experts with the subject or skill. The books provide explanations of the subject or skill on a level so that anyone who is not an expert can learn to do it or understand it. It’s almost ironic that the last verse of the iconoclastic Chapter 3 of the Gospel of John that contains such provocative theological propositions as “You must be born again” (vs. 7) and “For God so loved the world that he gave his only Son” (vs. 16) ends with this amazingly succinct statement of the gospel that even a dummy like me can understand. The verse clearly states that since we are all under God’s wrath, all one has to do is believe in Jesus, the Son of God, and obey Him to escape the wrath of God and have eternal life. If you don’t believe and obey, then God’s wrath remains on you. It’s that simple–you either have eternal life or you have God’s wrath! Don’t be a dummy and remain under wrath when you can have eternal life!
