When you want to rescue someone who won’t come when you call, you go to Plan B: You go get them yourself. That’s what God did for us. The Old Covenant couldn’t save anyone, not because there was something wrong with the covenant, but because there was something wrong with the people. They didn’t hold up their end. They couldn’t. So God made a new covenant where he does everything for us. Jesus came to live and to die and to rise again. God is the author of our faith. God saves us, because we could never save ourselves.
