Resurrection is the hope that out of death, life can emerge.

You haven't done enough to earn salvation. But Jesus did enough through his death, burial, and resurrection.

Is righteousness is a by-grace-through-faith reality, rather than a behavioral exercise?

Jesus was raised from the dead. The story is true. The evidence is overwhelming.

Why is the gospel “the power of God for salvation”? Why is “a righteousness from God revealed” in it?

Give it to me straight. Make it clear and easy to understand. Jesus did not always follow that formula.
