Tell the Truth

Week 4 | Sermon Series “But I say…”

Lead Pastor Todd Kaunitz


  • The God of truth wants His people to be people of truth.
  • Jesus’ righteousness leads us to become truthful people with character and integrity.
  • Willful deception is the by-product of our sinful disposition.
  • Sincere integrity is the outworking of gospel transformation.

Bible Text: Matthew 5:33-37

During our sermon series, we are learning that life in the Kingdom isn’t a moral code we try to live up to. It is a life Jesus produces in us through the power of the Holy Spirit.

Life in Jesus produces righteousness that transforms us from the inside out and impacts every area of our life. Today we will learn how it produces a life of character and integrity.

In today’s text, Jesus addresses the issue of a sinful life of deception versus a godly life of integrity. Consider these two statements:

  1. Willful deception is the by-product of our sinful disposition – Deceiving someone intentionally is the by-product of our fallen sinful nature. It is from the devil. For example, if you are in sales and you intentionally mislead a person about their purchase, it is sin. If you tell a person that financially they can afford something because ‘on paper’ they can but you know they really can’t, it is sin. If you say you are going to do something, but you have no plans to follow through, it is sin. Jesus says these behaviors reflect the evil one and it is a by-product of his influence in your life. Proverbs 12:22 says, “Lying lips are an abomination to the Lord, but those who act faithfully are his delight.”
  2. Sincere integrity is the outworking of gospel transformation – verse 37 says, “Let what you say be simply ‘Yes’ or ‘No’…” Notice that Jesus is not restricting any and all oaths. We operate in a world of contracts, business agreements, and court systems that requires oaths. What Jesus is saying is, “My followers will be so transformed by My righteousness that their integrity will not need an oath. They will not be any more truthful under oath or any less truthful not under oath. They will speak the truth. If they say they will, they will! If they say they won’t, they won’t.”


Jesus is not introducing a new concept. See Psalm 51:6; Zechariah 8:16-17; Ephesians 4:22-25. Now that we have been redeemed by Jesus, we must take off the old nature and put on the nature of Jesus.

How so? Through the renewing of our mind by the inward working of the Holy Spirit. What is the result of that? We put away all deceit and falsehood actively, willfully and obediently. We speak the truth to everyone. This sincere integrity is an outworking of the Gospel.

Do you realize how radically different we would stand out in culture by simply being this type of person? Being salt and light in the world isn’t just about going on mission trips and giving to people in need. It’s about having integrity, honesty, truthfulness. It’s about being dependable. Following Jesus in faithful truth sets us apart in society!


Action Steps:

  • Be Honest before God – Ask: Do I have a real relationship with God? Have I trusted God for my Salvation? Do I need to be baptized?
  • Be Honest with yourself – Ask: Where am I spiritually? Some of you are watching online because you are disconnected. It’s about pride and preference and not need. I invite you to get honest with yourself.
  • Be Honest in relationships – Ask: Are there areas of ongoing deception in my life? Do I need to confess any hidden sins to my spouse?

Jesus’ righteousness leads us to become truthful people with character and integrity. This is a missing ingredient in our world. Remember: this is no small thing for Kingdom people. God is a God of truth. He cannot lie! The God of truth wants His people, to be people of truth.
