Lying

The Ninth Commandment (2) Speak the Truth

This is one of the things that it means to be a Christian. As the outworking of the new life in Christ, Christians are to put off their old self and put on the new self and the new self is like God. One of the things that the new life in Christ enables us to do is to begin to reflect the character of God in our lives. One of the great goals of our salvation is that we will reflect the character of God in the way that we live our lives. This is perfected only when we are glorified, but it begins in the here and now, and it involves the power of the Holy Spirit working in us and our own efforts by means of that power.
