“You have heard that it was said, ‘You shall not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart. If your right eye causes you to stumble, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell. And if your right hand causes you to stumble, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into hell.
If you begin to read through the Bible, even through the gospel accounts of Jesus, you’ll find passages which are difficult, and make little sense at least to us. The more we read each part in the context of the whole, the better off we’ll be, the more able we will be to let a difficult reading sit. The last thing we should do is dismiss it out of hand as nonsensical. It may not make sense to us, or it may even be offensive. But we might need to read further and let it sit as we prayerfully consider.
For me it’s obvious in the above passage that Jesus was making a point. Although Christians have actually taken this literally in a physical sense, that is surely not what Jesus was getting at. But I will say this: Jesus is saying we need to deal with this sin ruthlessly, lest this sin deal with us in the same way.
Thankfully there are plenty of Scripture passages which are plainly instructive and encouraging to us. But we have to see those as well in the whole. The Christian faith is not about being happy, but blessed. It’s not about everything being great and pleasant in this life. It’s about following Jesus, come what may, and in doing so, dealing with the sin in our own lives, before we think for a second we can help someone else. It does no good to dwell on the precious promises, if we fail to take seriously the entire word, each and every part of it, even if we struggle to understand. God will help us understand what we need, to continue on the way he has for us. In and through Jesus.
