Our corrupt nature is like a spiritual birth defect that all of us are born with. “Behold, I was brought forth in iniquity, and in sin did my mother conceive me.” (Psalm 51:5). “For the intention of man’s heart is evil from his youth. “ (Genesis 8:21).
It is this sin nature that produces the evil that we hear like a broken record on our nightly news. Jesus speaks to this reality when he says, “and the evil person out of his evil treasure brings forth evil.“ (Matthew 12:35). What is this evil treasure? It is the iniquity, the sin, the evilness of our heart.
Understanding the source of evil in the world is crucial to solving the problem of evil in the world. If we accept this reality that evil comes from our corrupt sinful nature, our evil heats, then it changes how we approach the problem. For example if I have a headache, I take aspirin. However, what if I discover that my headache is caused by a brain tumor? Should I just keep taking aspirin?
So how does one attack the cancer of our corrupt sin nature? In Matthew 12:35, which I quoted above, Jesus also says this, “The good person out of his good treasure brings forth good.“ Therefore, the only way to swap evil for good is to swap evil treasure for good treasure. We must remove the old evil treasure and replace it with new good treasure. How is this done? Education? Therapy? Rules and regulations? Money? If history is any indicator, none of these things work. None of these things have the ability to reach into the core of a person and change who they are fundamentally.
How then is this done? It is not done by earthly means. It is only done by the powerful Grace of God through his Son Jesus Christ. This is the reason that Christ came to earth, to solve the issue of evil that enslaves all of us. It is only God who has the power to reach into the core of our being and change our treasure from evil to good.
The way this is achieved is by the power of the gospel being preached and the Spirit of God piercing a man's heart. Upon hearing the gospel and receiving the truth that it contains, a soul change occurs. God replaces our evil treasure with the treasure of His grace. From that point on, a man's life is forever changed. For the first time, his inclination is towards good, not towards evil. Why? Because out of his good treasure he brings forth good.
This is the answer to all the worlds problems. The Gospel. If you want to change the world, then first repent and place your faith in Christ. Second, go and make disciples through the preaching of Christ crucified. This is the only means by which we can truly eliminate evil in this world. Everything else is like taking aspirin for cancer.
