There is a principle at work here - and one that has been seen again and again in the world. The more the wicked increase in a society, the more that the society will turn toward wickedness. This is not a recent phenomenon - it has been happening ever since the fall of man. In fact, one of the most powerful examples of it was not long after man fell into sin.
We read in Geneis chapter 6 of this kind of situation. "Now it came about, when men began to multiply on the face of the land, and daughters were born to them, that the sons of God saw that the daughters of men were beautiful; and they took wives for themselves, whomever they chose." The progression here is fascinating to see. First the wicked began to multiply. You might wonder why I think the wicked multiplied - and not the godly. The reason for this is because man is sinful - and will always orient himself toward his sin and ungodliness unless God intervenes by His grace to change things. The next step was that the wicked began to modify - and they modified God's intention for marriage. They married at will - based on something other than God's plan. This led to the wicked multipliying even more. The god-desired role of the family was perverted and rather than pass on godliness - men began to pass on and even grow in his wickedness.
We read in verse 5 of that same chapter of Genesis, "Then the Lord saw that the wickedness of man was great on the earth, and that every intent of the thoughts of his heart was only evil continually." Two more things began to happen. The wicked began to magnify their wickedness. God saw that the wickedness of man was great on the earth. The original intent for creation was to magnify the Creator, God. Now it was filled with men who magnified the creation, man. The second thing that happened was the the Wicked began to meditate on their wickedness. Every intent of the thoughts of their heart became evil continually. God's desire was for men to meditate on Him and His Word - instead, they meditated on their godless desires - which led to even worse conditions.
The wicked then turned to mayhem and murder in their wickedness. God said the following to Noah about this in verse 13 of chapter 6 of Genesis. “The end of all flesh has come before Me; for the earth is filled with violence because of them; and behold, I am about to destroy them with the earth." James warns us in chapter 4 of his letter that the cause of our fighting is our lusts that wage war within us. This leads us to even kill so that we can fulfill our lusts that rage for more within us. The sad ending of all this is that the choices of the wicked led to the condemnation of the wicked. God destroyed that generation.
As we turn our attention back to our proverb - we see just what Solomon is communicating to his sons - and to all who would read these words. When the wicked increase, transgression among men increases as well. But in the end the righteous will see their fall. Wickedness cannot reign long in a land - it consumes it to a point of catastrophe. It did so in Noah's day - and we read that as it was in the days of Noah, so also it shall be in the days of the coming of the Son of Man. The ungodly will always be ungodly - and the wicked will seek to multiply their wickedness. But what is there for us to learn from this - just don't be wicked? No, there is a message for us today - one that will magnify the grace of God in the gospel.
How can we keep the wicked from increasing? Every time a child is born - another ungodly heart enters the human race. We are fallen - and we multiply into more fallen men and women over time. The answer lies in the gospel of Jesus Christ. This is the ONLY way that we can stem the tide of the wicked multiplying on the earth. We must multiply! We must be about sharing Jesus Christ with all who are around us. We must take the one thing that can take a wicked heart and transform it into a godly one. That one thing is the gospel of Jesus Christ! Jesus sent us into the world to make disciples of all the nations. As the early church took that mandate seriously they multiplied disciples - leading them to Christ - baptizing them as they identified with Christ - teaching them to obey all Jesus commands - and then doing it in each and every generation until the end of the age. This, and only this, can stand against the wicked and their wickedness multiplying in a society! May God give us grace to accept no substitutes in this matter - no political or social or military option which in the end will only fail. May we see that the glorious mandate to minister the gospel - and make disciples IS God's only answer for our world!
