Nevertheless I have somewhat against thee, because thou hast left thy first love. Remember therefore from whence thou are fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent. Revelation 2:4, 5
At the first the experience of the church at Ephesus was marked with childlike simplicity and fervor. The believers sought earnestly to obey every word of God, and their lives revealed an earnest, sincere love for Christ. They rejoiced to do the will of God because the Saviour was in their hearts as an abiding presence. Filled with love for their Redeemer, their highest aim was to win souls to Him....
But after a time the zeal of the believers began to wane, and their love for God and for one another grew less. Coldness crept into the church. Some forgot the wonderful manner in which they had received the truth. One by one the old standard-bearers fell at their post. Some of the younger workers, who might have shared the burdens of these pioneers, and thus have been prepared for wise leadership, had become weary of oft-repeated truths. In their desire for something novel and startling they attempted to introduce new phases of doctrine, more pleasing to many minds, but not in harmony with the fundamental principles of the gospel....
As these false doctrines were urged, differences sprang up, and the eyes of many were turned from beholding Jesus as the Author and Finisher of their faith. The discussion of unimportant points of doctrine, and the contemplation of pleasing fables of man's invention, occupied time that should have been spent in proclaiming the gospel. (The Acts of the Apostles, 578-580)
Reflection: Many Christians start out with much zeal in their newfound faith. Then with time, many lose that zeal and start backsliding. Let's recommit ourselves and be faithful until the end. Jesus is coming soon.
