God's Reward is
Independent of Our Abilities
nLuke 21:1-4 (NIV) As he looked up, Jesus saw the rich putting their gifts into the temple treasury. 2 He also saw a poor widow put in two very small copper coins. 3 "I tell you the truth," he said, "this poor widow has put in more than all the others. 4 All these people gave their gifts out of their wealth; but she out of her poverty put in all she had to live on."
nSee also Matthew 25:14-30, where the one with two talents was rewarded equally with the one with five talents.
