Can you really paint a true picture of God if you don’t maintain a biblically sound view of infidelity and divorce? Have you hated wickedness and loved righteousness? If so, then you must call sin, sin, as Jesus does.
You must call it sin in order to have the proper urgency about it and to stay free. You have to recognize it for what it is – a bear trap capable of crushing you and trampling your family and your friends. Sin affects your relationship with God and your relationships with others, so you have to call it what it is. How else can you walk normally in the midst of your relationships?
