The saying “the road to hell is paved with good intentions” is not found in the Bible. The saying uses “hell" hyperbolicly to highlight that what we think is right is not always truly right. What seems right to a person can still lead to
destruction (Proverbs 16:25) because the human heart is deceitful (Jeremiah 17:9). God alone sets the standard of what is right (Proverbs 3:5-6).
Salvation
(not going to hell) has nothing to do with having right intentions. People
can be sincerely devoted to God and still be wrong (Romans 10:2–3). Nor is
salvation based on doing the right works (Ephesians 2:8–9). Instead, it comes
through repentance and trusting in Jesus’ work (Romans 10:9–10).
When you push the first domino in a line of them, what happens? They all fall, one by one. But life isn't like those dominoes. Life is messy, people are messy, and mistakes and misunderstandings happen
along the way. Some of our best intentions end up with disastrous results. The saying “the road to hell is paved with good intentions” captures that paradox.
Regarding salvation, our intentions don't get us into Heaven, nor do they send us to Hell. We are born sinful and are God’s enemies (i.e., Psalm 51:5). We are on the path to hell from day one.
We can’t wish our way into heaven any more than we can work our way there. Our
intention might be to do good in this life, but if we try to do good without Christ,
regardless of our intention, we will awake in hell (Luke 16:22b–23).
Jesus came to
earth because we cannot save ourselves. Taking on a human nature
(Philippians 2:6–7), He never sinned once, being like us in every way except
for sin (Hebrews 4:15). But He took on the burden and punishment for our sins. All who trust in Jesus and His sacrifice will be saved
(Romans 10:9–10).
Don’t settle for good intentions when your eternity is at stake—good intentions can’t save you, but Jesus can. Stop planning to turn to Him someday, and choose today to trust, repent, and be made new.
