“If your right eye causes you to sin, 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 sin, 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.” Matthew 5:29-30
Jesus is still talking here about the command not to commit adultery. But He hyperbolizes the practical application of it.
In Biblical culture, anything on the right side of the body was considered honored [Mark 16:19; Acts 7:55-56; Romans 8:34; Ephesians 1:20; Colossians 3:1]. While the left hand was typically considered dishonored because of its hygienic function. So if the eye–which is the lamp that lets light into our whole body [Matthew 6:22]–and the honorable eye at that, gazes lustfully at others, we’re guilty of the sin of adultery.
Remember that God is transcendent. As humans, we tend to see good and bad, right and wrong in spectrums. We qualify things as kind-of-good and not-so-bad. But God does no such thing. Either it’s of God or it’s sin. Lustful eyes are symptomatic of a sinful heart.
So again, if the most honorable light source in our life fixates on sinful passions, we would be better off living this finite life half-blind, so that we don’t miss out on eternal life.
Now obviously, the struggle with lust can’t be associated with only one eye. We use both to look. So both are the offenders. Just like a person isn’t likely to commit sins of theft or adultery with one arm tied behind their back. But even if one did, the whole person would still be guilty of theft. By using a hyperbole–an exaggerated statement or claim not meant to be taken literally–Jesus emphasizes His point. It is the sin that needs to be cut out of our lives by whatever means necessary.
God made a covenant of circumcision with the patriarch Abraham and His chosen people, Israel [Genesis 17:1-25]. After the Exodus and throughout the New Testament, God let the people know that true circumcision needed to be of the heart [Deuteronomy 10:16 & 30:6; Jeremiah 4:4; Romans 2:25-29].
You see, circumcision is physically removing some unnecessary flesh that could create health problems. But we need to cut the love-of-this-world-flesh off of our whole heart–intellect, will and emotion–because it only leads to spiritual health problems. Jesus’ command to gouge out an offending eye or to cut of an offending hand has the same meaning.
Does God really want people to go around maiming themselves? Not at all! But He does want us to understand the seriousness of sin, to repent of it and to flee from it [Isaiah 59:2; Acts 2:38; 1 Corinthians 6:18]. In the end, it’s better for us to miss out on the emptiness of this finite life than to spend the rest of eternity regretting our lack of self-control.
We all struggle with a particular sin or another [Romans 3:23]. But we can ask the Holy Spirit to empower us to flee from it or to miraculously heal us and cut it out of our life. What sin are you in? Will you willingly give it to God? Or eternally regret it?
