I understand many people believe as you do. Can I ask a couple questions?
#1. When Jesus died on the cross did he die for all my sins, including the ones I haven't yet committed, or only the sins that I have already committed?
#2. If I died in the middle of telling a lie, before confessing my sin, would I go to hell?

Jesus died to pay the price for all the sins of those who will accept Him. The Bible states that God knows each one of us so intimately from the time He knit you together in your mother's womb until the end of time. Even knowing the depth of our greatest sin, He desires to draw you to Him, lest none should perish.

If you have accepted Jesus as your saviour, He has paid the price of spiritual death/hell for ALL of you sins. No man is capable of living a sin-free life, no matter how "good" they are. This is why Jesus offered himself as the sacrifice. The only unforgivable sin is to reject this offer.
Yes, this means that really, really bad people can go to heaven if they accept the offer just before death. But they will have missed the promise of an abundant life here on earth. The promise begins as soon as one allows Jesus to be the Lord, the ruler of their life.
Once you accept Him, the spirit will guide you to turn away from sin. You will still fail from time to time, but He will never leave you.
Hope this helps answer your questions. Thank you for listening.
