Mathew 21 Lesson

Telling The Truth And Acting On Faith


What is more important to God, saying we are going to do something, or actually doing it? In the Parable of the Two Sons (Mathew 21:28-32) Jesus tells of a father that had two sons.

The father said to the first son:

  • “Son, go work today in the vineyard.” - Mathew 21:28.

The child answered:

  • “I will not; but afterward he regretted it and went.” - Mathew 21:29.

The father came to the second son and said the same thing. The second son answered:

Jesus asks the question:

  • “Which of the two did the will of his father.” – Mathew 21:31?

Of course, this is a rhetorical question, and the chief priests and Pharisees quickly see the point that Jesus is making.

Telling the truth is so important to the life of a Christian. God does not tolerate lies, and we need to hold ourselves to a high standard of honesty. If people cannot trust the words that come out of our mouths, what sort of testimony are we making about our faith?


  1. “But let your statement be, ‘Yes, yes’ or ‘No, no’; anything beyond these is of evil.” Mathew 5:37,
  2. “Lying lips are an abomination to the Lord, but those who deal faithfully are His delight. ” -Proverbs 12:22,
  3. “But speaking the truth in love, we are to grow up in all aspects into Him who is the head, even Christ.” - Ephesians 4:15,
  4. “God is spirit, and those who worship Him must worship in spirit and truth.” -John 4:21,
  5. “Therefore, laying aside falsehood, speak truth each one of you with his neighbor, for we are members of one another.” -Ephesians 4:25.

So the first big takeaway from the Parable of the Two Sons is that we are commanded to tell the truth.

Before we look at the second takeaway from this parable, we will focus for a moment on the following scripture from the Book of James:

  • “But prove yourselves doers of the word, and not merely hearers who delude themselves.” -James 1:22.

What James is talking about here is the importance of doing what we say we are going to do and not being afraid to act for the Lord!


In the Parable of the Two Sons (Mathew 21:28-32) Jesus points out the son that did what his father told him to do is the one that did the will of his father. Even though he initially said he was not going to do it, he changed his mind, and eventually, he did exactly what his father asked him to do.

Life is like that sometimes. Sometimes we need a bit more time to think and pray about something before we act. But we must act! We cannot let procrastination or indifference prevent us from doing the work of the Lord! The Bible is clear about that. Consider the following scripture, also from the Book of James:

  • “What use is it, my brethren, if someone says he has faith but he has no works? Can that faith save him?  If a brother or sister is without clothing and in need of daily food, and one of you says to them, “Go in peace, be warmed and be filled,” and yet you do not give them what is necessary for their body, what use is that?  Even so faith, if it has no works, is dead, being by itself.” – James 2:14-17.

In Virtual Bible Study’s lesson entitled, “Obeying God And Acting On Our Faith, we made the following two points:

  1. “We can memorize the Bible from Genesis to Revelation, but if we do not act on what we have learned, our faith is useless.”
  2. “Every day we have opportunities to act on our faith. We may notice that somebody is having a difficult day and offer them words of encouragement. Or maybe we are asked to give somebody advice, and we quote a scripture. The ways that we can act on our faith are seemingly limitless.”


The Parable of the Two Sons is a fantastic example of how much importance God puts on doing, as opposed to saying we are going to do something.

Ben Franklin famously said, “Well done is better than well said.” (source: That is certainly true when it comes to our faith.

God wants us to be active followers of Jesus.  He also wants us to tell the truth and be people of our words that others can count on.

We will end today’s lesson with the following words spoken by our Lord and Savior, Jesus Christ. They remind us that, as Christians, we are to bring glory to God through our actions

  • “Let your light shine before men in such a way that they may see your good works, and glorify your Father who is in heaven.” -Mathew 5:16.



Jesus said if you know these things, happy are you if you do them. Sometimes we just have to take some action not worry about it too much


Amen Dan! Where is that scripture from?


John 13:17
