Although the blood of Christ cleanseth from all sin, some things cannot merely be undone. With or without forgiveness, sin has certain consequences.
Sin is not to be considered a light matter. In other words, it is not to be mocked. Only a fool would demonstrate this kind of behaviour toward sin.
There are many things in this life that are not sinful in and of themselves, but when they are misused they can be deemed as sinful or harmful.
Thoughts do not have to be wicked in order to be troublesome. Any thought contrary to faith will eventually cause a man to stumble. In Genesis 20:11, Abraham’s thoughts hindered his faith. He perceived that the fear of God was not in Gerar and decided to lie about the identity of his wife in order to insure his personal well-being. Rather than trusting God, he trusted his thoughts. Another example is Naaman. He refused to wash in the Jordan River because he thought that the prophet should have recovered his leprosy by coming out, calling upon the name of the Lord, and striking his hand over the place of leprosy (2 Kings 5:11). When a man trusts in his own thoughts over the words of God, that man shows a complete disregard for truth.
