In our lives we can't be forgiven of sin without someone having to intervene in our stead. There are always consequences for sin in our lives and there is a cost or price to pay for sin. Christ took the sins of all mankind and died for us. As a result we have the opportunity to be reconciled to God through His death. We as Christians therefore have to follow the example that Christ set when He was here on earth as a human being. We are to live as He did through the power of God's Spirit.
