5 questions · Understanding sin and its effects
Sin is not a popular topic. Modern culture prefers to speak of mistakes, issues, or negative behaviors. But Scripture uses stronger language. Sin is rebellion against God. It is missing the mark of His holy standard. It is the root cause of everything broken in the world and in you.
Understanding sin is essential to understanding the Gospel. If you don't grasp how serious sin is, you won't grasp how amazing grace is. The Bible's honest about human sinfulness. "All have sinned and fall short of the glory of God" (Romans 3:23). No one is exempt.
Sin entered through Adam and affects every person born since. You are not a sinner because you sin; you sin because you are a sinner. This is the doctrine of original sin—not a pessimistic view of humanity but a realistic one that explains why self-improvement always falls short.
The good news is that Christ came for sinners. He did not wait for you to clean yourself up. He died for you while you were still His enemy. His blood cleanses from all sin. His Spirit empowers you to fight sin's remaining power.
The questions below address what sin is, where it came from, and how to deal with it. May you understand your need more clearly and appreciate your Savior more deeply.

Questions About Sin
What is sin?
Sin is any thought, word, or action that falls short of God's perfect standard. The Bible describes sin as missing the mark (Romans 3:23), lawlessness (1 John 3:4), and rebellion against God. All humans have sinned and need God's forgiveness through Jesus Christ.
What does the Bible say about pride?
Pride is consistently condemned in Scripture as the root of many sins. 'Pride goes before destruction' (Proverbs 16:18). God 'opposes the proud but gives grace to the humble' (James 4:6). Satan fell through pride. We're called to humility, considering others more significant than ourselves.
What is the unforgivable sin?
Jesus called blasphemy against the Holy Spirit unforgivable (Matthew 12:31-32). In context, the Pharisees attributed Jesus' Spirit-empowered works to Satan. It's persistent, final rejection of the Spirit's testimony about Christ—not a one-time sin but hardened unbelief. If you're worried you've committed it, you likely haven't.
What is original sin?
Original sin is the doctrine that all humans inherit a sinful nature from Adam's first sin. Romans 5:12 says 'sin came into the world through one man, and death through sin, and so death spread to all men.' We're not just sinners because we sin—we sin because we're born with a sinful nature.
What does the Bible say about lust?
The Bible identifies lust as sinful desire that goes beyond normal attraction. Jesus said looking at someone lustfully is adultery of the heart (Matthew 5:28). First John 2:16 warns against 'the desires of the flesh.' Lust objectifies others and enslaves the mind. Scripture calls believers to purity, self-control, and fleeing temptation (2 Timothy 2:22).
