A Disciple of Jesus Loves One Another
"A new commandment I give to you, that you love one another; as I have loved you, that you also love one another. By this all will know that you are My disciples, if you have love for one another."
Christians are not under the law - there is no 'thou shalt not'; but rather we seek to please the Father by loving one another, and in doing so we keep from those things that are contrary to God's pleasure, such as lying, steeling or adultery. In this our motive is our love for God (Matthew 22:37; Mark 12:30), not the avoidance of punishment.
