O generation of vipers, how can ye, being evil, speak good things? For out of the abundance of the heart the mouth speaketh.” (Matthew 12:34, KJV)

The Bible illuminates a pivotal truth: the deep connection between our hearts and our words. This concept, relevant to both believers and non-believers, underscores our Christian responsibility to utilize it for our spiritual growth rather than succumb to its adverse effects.

Initially, we must understand what Jesus means by “out of the abundance of the heart, the mouth speaks.” Context is essential here. When the Pharisees criticized His ministry (Matthew 12:24), alleging He cast out demons by Beelzebul, Jesus responded. Their blasphemy was a manifestation of their hearts’ corruption.

Jesus elaborates on this idea, stating,

“A good man out of the good treasure of his heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.” (Matthew 12:35, KJV)

His point is clear: the contents of one’s heart (treasure) manifest through their words. Our herats are like a tree that bear fruit consistent with hits nature. An evil tree will bear evil fruit—by default. But a good tree will bear good fruit( Matthew 12:33). Evil intentions lead to blasphemy, while a good heart yields good fruit(words).

But what constitutes the ‘treasure’ in our hearts? In verse 25, Jesus, perceiving their thoughts, implies that this ‘treasure’ comprises our thoughts, emotions, and desires.

Interestingly, the term “evil” in this context warrants a deeper examination. It might be easy to equate evil solely with overt sins such as murder or hatred. However, the Scripture presents a broader perspective. While these actions certainly embody evil, the concept extends further. This is illustrated in Matthew 9:5, where the Pharisees, upon hearing Jesus forgive sins, thought in their hearts that He was committing blasphemy. Jesus confronts them, asking, “Why think ye evil in your hearts?” So evil in this context is wrongful, sinful, or ungodly thoughts, feelings, and desires.

Let’s conclude with a powerful affirmation of this truth from Mark 11:23. While evil in the heart (evil thoughts) produces blasphemy, good in the heart (faith) produces miracles (words of power)! Even in our salvation, out of the abundance of good in our hearts (faith in Jesus), the mouth spoke and confessed Jesus as Lord, and we became saved.

Every spoken word reflects your thoughts, feelings, and desires, either positively or negatively. Strive to use your speech to bear good fruit in areas such as relationships, finances, ministry, family, and health.

Meditate

What does Jesus mean by “evil” in Matthew 12:34 above?

Apply the Word

The first place to put this principle to work is to fill our hearts with good. So fill your heart with faith, love, joy. And when we do, our mouths will speak out of this abundance and bear good fruit.

Pray

Ask the Lord to help you fill your heart with an abundance of divine goodness.
