Consider the following points.

 - What do know about the Bible and do you believe it? Not much? Then read with an open heart and ask God to give you a mustard seed Faith to Believe.
 - What do you know about after life? None? Then the more you need to pay attention, for today might be your last!
 - About the rich man's story, running for his life, worried for his Eternal Security - Mark 10:17-23
 - Confirmation of Salvation through Christ Only - Acts 16:30-32, Romans 10:13

Common Belief today is, i'll do good and perhaps in certain time ill earn enough merit to be accepted of God and be free from the fiery Hell - Proverbs 14:12

Question now is, how do you know what you're doing is right and good and when will you know whether you've done enough so you could obtain mercy from God?

 - Faith can save us? Yes! - Eph 2:8-9
 - Story of the Thief, Faith in Action - Luke 23:39-43
 - Why Faith not Works? - Galatians 2:16
