I wanted to mention the parable of the talents how I used to view this parable. I won't post it, because I trust you already know it, and if you don't, I ask you to go and read it with this in mind.
I think its interesting that if your life about making enough talents to please God, you end up seeing your master the way the wicked servant perceived his master to be: A hard man.
If you see God as a hard man, then you will get a hard man on the day of judgment. If you insist on putting your hope in the law, you will reap consequences of breaking it.
So it won't be a question of "What did you do for Jesus?" on judgment day, but rather, "What did you believe jesus did for you?"
Many will boast of what they did for Jesus on that Day (Matthew 7:21-23). But only those who know him will enter the kingdom.
