Question 1

What does it mean that a tree is known by its fruit in this passage?

Accepted Answer

When Jesus says a tree is known by its fruit, he is using a simple picture to explain people’s lives. A good tree makes good fruit, and a bad tree makes bad fruit. In the same way, a person’s words and actions show what is really in their heart. The Pharisees claimed to be devoted to God, but their harsh, twisted words about Jesus showed a bad “tree.” This verse is not about becoming perfect, but about honesty: what comes out of us over time reveals what we truly are inside.

Question 2

Why does Jesus call them a generation of vipers?

Accepted Answer

Calling them a “generation of vipers” is very strong language. A viper is a poisonous snake, so Jesus is saying their hearts and words are like hidden poison. They claimed to be holy leaders, but they were spreading harm by twisting God’s work and speaking against the Spirit’s power in Jesus. This name unmasks their hypocrisy. They were proud of being Abraham’s children, but their speech and behavior showed a different family likeness, one of deceit and spiritual danger to others.

Question 3

What does “out of the abundance of the heart the mouth speaketh” mean?

Accepted Answer

“Out of the abundance of the heart the mouth speaketh” means that our words spill out from what fills our inner life. The heart here is our inner self, our thoughts, desires, and beliefs. When the heart is being shaped by God’s grace, good and helpful words come out. When the heart is left in its natural, sinful state, bitter, proud, or empty words come out. A person might fake good talk for a while, but over time their regular speech shows what is really stored inside.

Question 4

What is the good treasure and evil treasure of the heart?

Accepted Answer

The “good treasure” of the heart is the inner store of grace God gives: trust in him, love for what is right, and the desire to honor him. A person with this treasure brings out words that build up, point to God, and do good. The “evil treasure” is the natural, unchanged heart, full of unbelief, pride, and selfish desires. That person brings out slander, empty talk, or words that push people away from God. Jesus is saying our hearts are like chests, and our words show what is stored there.

Question 5

What are idle words, and why will people give account for them?

Accepted Answer

Idle words are careless, empty words that do no good. They are not just jokes, but speech that is useless, unkind, or thoughtless, that wastes the time God gives or stirs up harm instead of help. Jesus says people will give account for every idle word in the day of judgment to show that God cares about all our speech, not only our deeds. Our words matter because they reveal what is in our hearts, and they either agree with God’s truth or push against it.

Question 6

How can someone be justified or condemned by their words?

Accepted Answer

When Jesus says, “by thy words thou shalt be justified, and by thy words thou shalt be condemned,” he is not saying we earn God’s favor by talking well. He is saying our words will be used as evidence of what we really are. A heart that trusts God and receives Jesus will confess him and speak of him with reverence. Those words show a person belongs to God. A heart that rejects him will speak against him, twist his work, or stay cold and careless. Those words show a person remains under judgment.

Question 7

What was happening when Jesus spoke these warnings about speech?

Accepted Answer

Jesus spoke these words right after religious leaders said he cast out demons by the power of an evil spirit. They saw a clear work of God in setting a man free, but instead of honoring God, they explained it in the worst way. In that setting, Jesus warns that such speech springs from a bad heart and will be judged. The bigger scene is a clash between Jesus’ true authority and the leaders’ jealousy and fear of losing their place in front of the people.

Question 8

How does this teaching about words and the heart apply today?

Accepted Answer

This passage still speaks very directly. It invites us to listen to our own words as a mirror of the heart. Habitual gossip, constant complaining, tearing others down, or treating holy things lightly show something is off inside. On the other hand, steady, humble, honest speech that honors Jesus points to a heart being changed by God. The answer is not to polish our talk on the surface, but to seek a renewed heart from God and then let that new life shape how and why we speak.
