Very few people will die to save the life of another person, even if that other person is a good person. If the person is a very good person, then someone might be willing to die for that person.
I mean that while we were God's enemies, God made friends with us through the death of his Son. So surely, now that we are God's friends, God will save us through his Son's life.
And not only will we be saved, but we are also very happy now. We are happy in God through our Lord Jesus Christ. It is because of Jesus that we are now God's friends.
