The Sin of Deceit

Preacher:
Passage: Matthew 5:33-37, Psalm 15
Service Type:

Introduction

  • We have been looking at the Sermon on the Mount
    • In recent weeks – looking at very searching passages
    • We have looked at anger and lust
  • Today looking at the sin of deceit/lying
    • We can all say that we have lusted, been angry without cause, lying
    • Some have confessed great problems in these areas
    • Jesus spoke plainly about the dangers of such sin
    • Today’s passage is equally convicting – Matt 5:33-37
      • We will look at v31-21 another time
      • We will look at swearing oaths
  • Reading Matt 5:33-37
  • Our world is in a crisis of truth
    • Fake news, fact checkers, bias
    • We must filter the news through the word of God
      • Example of justice, the sanctity of human life, pride & boasting
    • Be careful how much you take in
  • Looking at the issue of truth and the sin of deceit
    • Jesus was concerned that there was much falseness in Israelite society
      • People were taking cheap oaths … often with no intention of doing so
    • Jesus says no need to swear oaths: simply say yes or no
      • Do not make excuses
      • Do not add to your words
      • Anything more is from the devil
    • Lying is serious
      • Prov 12:22, Rev 21:8
  • Overview:
    • The meaning of Jesus words
    • How it applies to us

The meaning of Jesus words

  • "You have heard …"
    • The Pharisees had twisted the interpretation for their benefit
    • Jesus gives a clear and true interpretation
  • Do not swear at all – our word should be our bond
    • Can people trust you?
    • Do you keep your word?
    • Are you prepared to say no?
    • Are you a person of your word?
  • Jesus gives a summary statement of words from Leviticus, Deut 23:21-22, Numbers
    • If you do not fulfil a vow – it will be sin to you (Deut)
      • We should take vows carefully and not vow lightly – examples
    • In the Bible there are instances of people taking vows
      • Example of Joseph – to take his body from Egypt to Israel – this vow was fulfilled (about 440 years later)
  • The Pharisees were using a loophole to get out of ‘vowing to God’
    • Jesus says not at all – all things belong to God
      • Earth, heaven, your hair
      • It is foolish to think you can get around this
    • Reading Matt 23:16-18
      • "Woe to you, blind guides, who say, ‘Whoever swears by the temple, it is nothing; but whoever swears by the gold of the temple, he is obliged to perform it.’ Fools and blind! For which is greater, the gold or the temple that [i]sanctifies the gold? And, ‘Whoever swears by the altar, it is nothing; but whoever swears by the gift that is on it, he is obliged to perform it.’ Fools and blind! For which is greater, the gift or the altar that sanctifies the gift?"
      • Trying to split hairs – explanation
    • Jesus cuts through this hypocrisy and exposes it
      • Do you need to keep saying ‘honestly’, ‘I swear’
      • We should analyse our words
  • Jesus is not doing away with oaths
    • He answered under oath in ‘court’
    • The apostle Paul makes a vow – Acts 18:18
    • The apostle Paul had witnesses of his actions
    • We still have oaths – court, marriage vows,
    • But we must fulfil our oaths
  • Jesus is concerned for truth in the inward parts
    • Does not everyone lie?
    • How foolish to compare ourselves to others
    • v48 – compare yourself not to others but to God
      • We can never be perfect but consider God’s standard
      • Do not make excuses – examples
  • This is extremely convicting
    • Believers – we ask for God’s help to change
    • Unbelievers – ask God to create a new heart in you
    • It is difficult to know how to respond at times
      • Jesus often asked questions of others
    • Jesus went to the cross to bring forgiveness of sins – if we trust in Him as Lord and Saviour
      • We are filled with God’s righteousness
    • Jesus can change us
    • The book of James talks about the difficulty/danger of the tongue
      • Explanation
  • This teaching returns to two of the Ten Commandments – taught in a personal way
    • Not to take the Lord’s name in vein – 4th Commandment
    • Not to swear falsely – 9th Commandment
  • James 5:12 repeats Jesus’ teaching: "But above all, my brethren, do not swear, either by heaven or by earth or with any other oath. But let your “Yes” be “Yes,” and your “No,” “No,” lest you fall into judgment"
    • We will be judged for our idle words
      • Hence we should paid heed to what Jesus says
      • Do not embellish, exaggerate or make excuses
      • Simply say yes or no
      • Do not be like the devil who is the ‘father of lies’
  • Sometimes oaths are to our own hurt
    • Example
    • Psalm 15:4
      • This Psalm ultimately points us to Jesus Christ
      • God will not hear our prayers if we regard iniquity in our hears (Psalm 66:18)
        • Confess your sin to Jesus and come to God in His name

How it applies to us

  • There is a reverse of the above
    • Grace, kindness, truthfulness
    • Let us be known as people of our word, integrity and loving/honouring Jesus
    • Do our lives match our words?
    • May God help us in this
