In the Sermon on the Mount, Jesus teaches that the act of looking at someone with lustful intent is equivalent to committing adultery in one's heart (Matthew 5:27-28). This teaching emphasizes the importance of purity in one's thoughts and intentions, not just actions.
The Biblical Definition of Adultery
Adultery is typically understood as the act of engaging in sexual relations with someone other than one's spouse. However, Jesus' teaching expands this definition to include the emotional and mental aspects of adultery. In essence, Jesus is saying that the sin of adultery begins long before the physical act, and that it is rooted in the desires and intentions of the heart.
The Heart of the Matter
The Bible teaches that the heart is the source of all human actions, including sin (Proverbs 4:23, Matthew 15:18-20). When we look at someone with lustful intent, we are allowing our hearts to be consumed by sinful desires. This can lead to a pattern of thinking and behaving that is contrary to God's will.
The Importance of Purity
Jesus' teaching emphasizes the importance of purity in our thoughts, words, and actions. As followers of Christ, we are called to live a life of holiness and purity, not just in our outward behavior, but also in our inner thoughts and desires.
Practical Applications
So, how can we apply this teaching to our everyday lives? Here are a few practical suggestions:
Guard your heart: Be mindful of the things you watch, read, and listen to, and avoid exposing yourself to material that can stir up lustful thoughts.
Practice self-control: When you find yourself tempted to look at someone with lustful intent, look away and redirect your thoughts to something pure and wholesome.
Cultivate a heart of purity: Focus on developing a heart of purity and holiness through prayer, Bible study, and fellowship with other believers.
Jesus' teaching on lust and adultery reminds us that sin begins in the heart, and that we must be mindful of our thoughts and intentions. By guarding our hearts, practicing self-control, and cultivating a heart of purity, we can live a life of holiness and purity that honors God.
