Jesus Teaches About the Defilement of the Heart

This truth addresses the heart of the matter, highlighting that it is not external factors, such as food, that defile a person, but rather the words and intentions that come from within. Paul writes in Romans 8:28 that all things work together for good for those who love God, and this principle applies to the way we speak and think. The words that come out of our mouths reveal the condition of our hearts, as Jesus taught in Matthew 15:18-19, where He says that evil thoughts and words come from the heart. This doctrine is significant because it emphasizes the importance of guarding our hearts and minds, recognizing that our words have the power to build up or tear down.

The Reformed perspective on this matter is rooted in the understanding that humanity is fallen and sinful, and that our words and actions are often tainted by this sinfulness. However, through the power of the gospel and the work of the Holy Spirit, believers are being transformed and renewed, enabling them to speak words that are edifying and glorifying to God. A common misconception is that this truth implies that external actions are unimportant, but rather, it highlights the importance of a regenerate heart that overflows with gracious and loving words.

This truth has significant implications for the way we interact with one another, and as a pastor, it is essential to encourage believers to examine their hearts and minds, recognizing that their words have the power to bring life or death. By pointing to the gospel and the transformative power of Christ, we can encourage one another to speak words that are filled with grace, love, and truth, ultimately bringing glory to God and edifying one another.
