Blessed are the Pure in Heart, For They Will See God (Matthew 5:27–30)


Blessed are the Pure in Heart, For They Will See God (Matthew 5:27–30)

Sexual sin. It is a destructive issue we face more often than we like to admit.

Whether it is lust, pornography, adultery, same-sex attraction, or any number of other desires that deviate from God’s good design, we are inclined to bury these parts of our lives in the dark. Yet, in Sermon on the Mount, Jesus wisely and lovingly shines a light on our hearts. Getting to the heart of sexual sin, he explains what lust is, where it comes from, and how, by God’s new covenant grace, it be put to death.

This Sunday we looked at Matthew 5:27–30 to learn from Jesus what lust is and how to combat it. And the answer, which may or may not come as a surprise, is to look more at the beauty and goodness of God than to merely turn away from the flesh. While external barriers and accountability are helpful, it is a heart full of Christ that empowers us to flee from sexual lust.

Matthew 5:8, 27–30

“Blessed are the pure in heart, for they shall see God.

“You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart. If your right eye causes you to sin, tear it out and throw it away. For it is better that you lose one of your members than that your whole body be thrown into hell. And if your right hand causes you to sin, cut it off and throw it away. For it is better that you lose one of your members than that your whole body go into hell.
