Often times we can get so busy doing the Lord’s work we neglect the Lord in the process. In Revelation the Church of Ephesus had things they were doing well such as laboring hard for Jesus and disdaining the lifestyles and teachings of those who promoted sin by means of “grace” however they missed Christ in the midst of works, working hard but abandoning the Love of God in the process.
Revelation 2:4-7 Yet I hold this against you: You have forsaken the love you had at first. Consider how far you have fallen! Repent and do the things you did at first. If you do not repent, I will come to you and remove your lampstand from its place. But you have this in your favor: You hate the practices of the Nicolaitans, which I also hate. Whoever has ears, let them hear what the Spirit says to the churches. To the one who is victorious, I will give the right to eat from the tree of life, which is in the paradise of God.
Christ said he would remove their “lampstand” which I suppose could mean their position of influence or effectiveness. In reality this will happen to us all when we do not abide in the vine! We cease being effective as a light to a dark world!
