Joh 13:34 A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.
35 By this shall all men know that ye are my disciples, if ye have love one to another.
We have seen that the most important command for a Christian is to have a fervent love for other Christians. This love is more important than other issues, even though the other issues are important. In the above passage, we tend to emphasize verse 35, but there's something in verse 34 that we miss. When Jesus commanded us to love one another, He explained "as I have loved you."
We're to love each other just as much as Jesus loved us. Jesus doesn't become enemies with Christians over dress codes, music, or non-Gospel doctrines. He didn't commit sin in order to get along with Christians, but He didn't become their Enemy, either.
