You answered YES to the most important question in life! The Bible tells us that we CAN know for sure that we're going to Heaven! Take a look:

"These things have been written to you that
you may KNOW that you have eternal life" 1 John 5:13

QUESTION #2:
Suppose you were to die tonight and stand before God and He were to say to you, "Why should I let you into My Heaven?" What would you say?

I've tried to live my life good.

I'm basically a good person.

I've gone to church all my life.

I don't deserve to go anywhere else.

I've tried to live my life by the 10 Commandments.

I cannot enter Heaven on my own, I need help.

I don't know what I would say.
