Why Is Sin So Bad?

Text: Genesis 4:6-7

God warned Cain about sin – its desire was for him, to control him and ultimately to destroy him. Cain did not heed God’s warning about the danger of sin. We need to pay attention to the reasons given in the Scriptures about why sin is so bad for us.

Sin is Fighting Against Us

  • Peter warned about fleshly lusts waging war against us (1 Peter 2:11)
  • Notice how Paul describes this war (2 Corinthians 10:3-5) – obedience is the goal (opposite of sin)
  • Many powerful forces are fighting for sin (Ephesians 6:10-13) – we must be prepared

Sin is Trying to Kill Us

  • God warned man not to eat of the tree of knowledge of good & evil (Genesis 2:17) – the penalty was death
  • Satan denied the penalty (Genesis 3:4) – yet death was the result: physical & spiritual (Genesis 3:22-23)
  • The penalty of sin is death (Romans 6:23) – eternal punishment; separation from God
  • The goal of sin is death (James 1:14-15) – it doesn’t offer us anything good, despite its deceitful promises

Sin is Insulting to God

  • Contrast between the punishment of the Old Law with punishment deserved today (Hebrews 10:28-29)
  • Jesus brought grace (John 1:17) – but this grace is not a license to sin (Romans 6:1-2; Jude 4)
  • It is insulting to the Spirit of God for us to continue in sin – to illustrate this, sin is compared to marital infidelity (Jeremiah 2:20-24; 3:1-2)

Sin is an Affront to God’s Glory

  • Familiar passage about the universal problem of sin (Romans 3:23) – but what do we do when we sin? … we “fall short of the glory of God
  • Sin is a violation of God’s law (1 John 3:4) – but it goes deeper than mere “rule-breaking”
  • God did not give us a random set of rules “just because” – His laws come from His character & glory (Romans 1:16-17)
  • God has taught us how to live godly (Titus 2:11-12) – sin is a complete disregard of that

Sin is Opposed to Our Calling

  • Called Christians (Acts 11:26) – to be Christ-like (1 Peter 2:22)
  • Saints by calling (1 Corinthians 1:2) – set apart for God’s purpose (cf. 1 Thessalonians 4:7)
  • Called to freedom (Galatians 5:13) – freedom from what? … sin (Romans 6:18)
  • Walk worthy of our calling (Ephesians 4:1-2; 2 Thessalonians 1:11)
  • Make certain of your calling (2 Peter 1:10) – by adding to our faith these characteristics (2 Peter 1:5-7)
  • Sin is completely opposed to all of this


  • Sin is not something to be ignored as if it is no problem or no threat – sin is a huge problem & we need to be fighting against it
  • As with Cain, sin is “crouching at the door,” waiting for an opportunity (cf. 1 Peter 5:8) – we must be watchful & faithful
  • If sin enters our lives, we must quickly & thoroughly eliminate it
