Expositor's Bible Commentary Commentary Matthew 5:30

"And if thy right hand causeth thee to stumble, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not thy whole body go into hell." — Matthew 5:30 (ASV)

The radical treatment of parts of the body that cause one to sin has led some (notoriously the church father Origen) to castrate themselves. But that is not radical enough, since lust is not thereby removed. The “eye” is the member of the body most commonly blamed for leading us astray, especially in sexual sins (cf. Numbers 15:39; Proverbs 21:4; et al.); the “right eye” refers to one’s better eye. But why the “right hand” in a context dealing with lust? More likely it is a euphemism for the male sexual organ.

Cutting off or gouging out the offending part is a way of saying that Jesus’ disciples must deal radically with sin. Imagination is a God-given gift; but if it is fed dirt by the eye, it will be dirty. All sin, not least sexual sin, begins with the imagination. Therefore what feeds the imagination is of maximum importance in the pursuit of kingdom righteousness . The alternative is sin and hell, sin’s reward.
