The good news is that we are so lost and broken that we cannot find God or fix ourselves, so God has come to find and save us. To do that he sent his Son, Jesus Christ, who was fully God, but lived an ordinary human life, except that he never did anything wrong. He kept all of God’s laws, both outwardly and in his heart.
In addition to giving us the credit for his perfect life of obedience, Jesus willingly at the cross took the punishment that we deserve for our imperfect, rebellious lives. When he rose from the dead, Jesus demonstrated that death had no hold on him, nor on any who entrust their lives to him. Christianity therefore, is not a set of rules to live by or a philosophy, but is essentially about a person, Jesus Christ. A Christian is someone who loves and trusts Jesus.
This acceptance into the family of God transforms us. Since we are no longer trying to earn God’s approval, we are free to love him and worship him purely out of gratitude and joy. We serve him, not in order to be saved, but because we are already saved. The more we delight in his love, the more we learn over time to to love others in the way Jesus has loved us.
