The Lord Jesus said, "My sheep hear my voice, and I know them, and they follow me" (Jhn 10:27). It is also prophesied many times in Revelation, "He that has an ear, let him hear what the Spirit says to the churches." The voice and words of the Spirit are the voice of the Lord, and it is God's sheep who will recognize God's voice. What practice, then, is most important for Christians as they welcome the coming of the Lord?
