Can a True Believer Commit Serious Sin?

1) Direct answer
Yes—in the sense that a true believer, still in this flesh, can fall into a serious wrong. No—in the sense that he cannot continue in it, excuse it, or be at peace with it. The life of God in him will drive him to repentance and restoration.

2) Scriptural explanation
- The Bible says, “Whosoever is born of God doth not commit sin… and he cannot sin, because he is born of God” (1 John 3:9; 5:18). That speaks of a nature that will not practice or live in sin.
- Yet it also says, “If any man sin, we have an advocate with the Father, Jesus Christ the righteous” (1 John 2:1). So a believer may stumble, but he is not left there.
- David fell grievously, but cried out and was restored (Psalm 51). Peter denied the Lord, wept bitterly, and was restored (Luke 22:61-62; John 21).
- “Sin… because they believe not on Me” (John 16:9). Sin at its root is unbelief. The born-again heart believes the Word and cannot settle in unbelief.
- “Shall we continue in sin? God forbid… Sin shall not have dominion over you” (Romans 6:1,14).
- A real son is chastened when he errs (Hebrews 12:6-8). God corrects His own.
- If we confess, He forgives and cleanses (1 John 1:9). The Spirit seals unto the day of redemption (Ephesians 4:30).

3) Simple clarifying logic
Now notice, the new birth activates God’s seed in the soul. That inner life says Amen to every Word and cannot deny it. The outer man may stumble, but the inside man cannot live in rebellion. A sheep may fall in mud, but it will not wallow there; it cries to be washed. If a person can live in willful, ongoing sin without conviction or chastening, the Scripture says that is not sonship (Hebrews 12:8). But if he is God’s, conviction strikes, godly sorrow works repentance, and he is restored to walk in the light.

4) Reinforcing statement
So a true believer may fall, even seriously, but he will not remain in sin. The seed of God in him breaks the dominion of sin, brings confession, correction, and a clean walk with God.

...tonight, is the dissolver of doubts! Do you believe that? The dissolver of doubts. Now, the blood of Christ takes away each stain, the stain of doubt. There's not a greater sin in the world than unbelief, "For he that believeth not, is condemned already." Is that right? "He that believeth not is condemned." There's only one sin, and that's unbelief. Smoking's not a sin, cursing's not a sin, committing adultery's not a sin, lying is not a sin. That isn't sin, that's the results of unbelief. Unbelief---you do it beca...

When their eyes were opened

What is sin? Unbelief. Smoking, drinking, committing adultery, lying, stealing, that's not sin. That's the attributes of sin. You do that because you're an unbeliever. If you was a believer, you wouldn't do that, see. Just because you quit drinking, and quit smoking, and quit drinking and committing adultery, that doesn't make you a Christian. You're a Christian because you are a believer, see. You are a sinner, you do the things that you ought not, because the life that's in you makes you do it. The tree's known b...
