Yet for all the talk about being good, still no one can answer the fundamental question: What level of good is good enough? Bizarre. At stake is our eternal destination, yet we are more confident about lasagna recipes than the entrance requirements for heaven. God has a better idea: “For by grace you have been saved through faith, and that not of yourselves; it is the gift of God” (Eph 2:8). We contribute nothing. Zilch. As opposed to the merit badge of the Scout, salvation of the soul is unearned. A gift. Our merits merit nothing. God’s work merits everything.

i like it, it really irritates the nature of the beast in us, funny how we have to labor to rest,so many times the beast in me fights hard for credit. I always liked the expression {its the nature of the beast} My father used it a lot, when i ask why someone did what they did, he would say its the nature of the beast.
