What does it mean to not only know who Jesus is, but to follow him? God gives authority to prophets in the Old Testament to speak in His name, but there are consequences if they overstep and speak more than he gave them to speak. In the Gospel, Jesus amazes people by the authority with which He teaches and the surety with which He casts out unclean spirits. And in our Epistle, the early church is working out the freedom such authority gives them, but Paul warns that there are consequences if their freedom oversteps their love for fellow Christians. It is not enough for us to know who Jesus is (even the unclean spirits recognize Him), but we must follow Him. We must walk in truth and love; set free by the truth, but confined by the practice and character of the holy and loving God that we follow.
