This sermon examines Jesus' teaching in the Sermon on the Mount regarding the seventh commandment, arguing that adultery is fundamentally a matter of the heart rather than merely a physical act. The central message is that lust is a disordered desire that originates in the inner man, requiring believers to guard their eyes and imaginations as gateways to the soul. The preacher urges a radical approach to sin, using Christ's hyperbolic language of removing eyes and hands to illustrate the necessity of taking serious, decisive action to cut off access points to temptation. While acknowledging the dire consequences of uncontrolled sin, the message ultimately points to the grace of Jesus Christ, who cleanses believers and empowers them to pursue holiness. The sermon concludes with practical applications, encouraging the removal of sinful gateways and the replacement of covetous desires with genuine love for one's spouse and, most importantly, for the Lord Jesus Christ.
