What was the church at Ephesus in Revelation lacking despite having correct doctrine and discipline?

Despite having correct doctrine and discipline, the church at Ephesus in Revelation was lacking love. The Lord's letter to that church identified no love as their major deficiency. Correct doctrine and perfect discipline count for nothing without love, as Scripture teaches.

Les explains that the letter to the church at Ephesus in Revelation shows they were correct in everything: their doctrines were straight and their discipline was in order. Yet as the Lord Jesus wrote or spoke that letter to that church, their major lacking was no love. Les emphasizes that it does no good to have all doctrines straight or perfect discipline if there is no love, because then it counts for nothing. This connects to Paul's point to the Corinthians that even understanding all mysteries or having faith that could remove mountains without love amounts to nothing.

Revelation 2:1

Unto the angel of the church of Ephesus write; These things saith he that holdeth the seven stars in his right hand, who walketh in the midst of the seven golden candlesticks;

What was the Ephesian church in Revelation lacking despite being doctrinally correct?

Despite doctrinal correctness and ordered discipline, the Ephesian church addressed in Revelation was lacking love. Its doctrines were straight and its discipline in order, yet without love those things counted for nothing. The Lord's letter identified this absence of love as the church's major deficiency.
