I do believe that I will be rewarded for any good things I have done through Christ's Holy Spirit.  God is a rewarder and He gives honor and blessing to those who have faith.  He delights in such things since He is ever so much more forgiving and generous than we can ever be.  He delights in life and love and goodness.

Hebrews 11 proves this. The "faith hall of fame" includes many sinners, each and every one.  But the Holy Spirit did not move the author to write about them with a judging heart.  Only their faith and acts of faith are mentioned.  Noah being drunk and naked, Abraham lying and putting his wife at great risk twice, Sarah telling Abraham to sleep with her maid and then sending that woman and her child into the desert to die,  Jacob's many deceptions and manipulations, Moses' murder of the Egyptian and his hitting the rock in anger, misrepresenting God, Rahab's years of prostitution, Gideon's fear and requiring proof from God, Samson's arrogance, fornication and disobedience and grief to his parents, David's adultery and murder of his own best commander, etc., etc.   

Their sins are remembered no more, and they are rewarded for their faith.  That is the God we shall meet.  He knows that it is "impossible for us to please God".  Only we ourselves esteem ourselves so highly that we expect ourselves to earn His favor.  

I have abandoned that delusion.  "In Him we live, and move, and have our being."  I swim in His grace, take unto myself His mercy through His blood, and have no expectations of doing "any good thing"  unless it comes "from Him, by Him, and through Him".  He is the Alpha (Creator) and Omega (Rewarder) of my life.  He is my Father and my God, and I rely on Him alone.
