(Pro 21:18 KJV) The wicked shall be a ransom for the righteous, and the transgressor for the upright.
This is a difficult verse. It is easy to turn to a totally wrong understanding, such as killing wicked people can pay for the sins of the spiritual people. If taken out of the moderating influence of the rest of scripture this could lead to danger and violence. It must mean something else.
One possible understanding is that God bestows His blessing on cultures and nations that have enough spiritual salt and light. Again this is dangerous because we, as Americans, like to say we are special in God’s eyes. This understanding can be a source of arrogance and sinful pride.
At the same time, if you were to do a historical map of areas that have contained a large minority of people who worship and obey the God of the Bible, I think you would see a pattern of stability, peace and prosperity in comparison to the rest of the world. The United States at one time had such a minority. I am not sure we do any more. I am guessing that if financial collapse and chaos is in our future it will be because the salt has been removed or rendered tasteless.
So? If you care about your children or the future of this nation let me recommend that you seek to be salt. Every grain makes a difference.
