In the Scriptures we can find a passage that tells us about a church that was in Ephesus and with which the Lord was not pleased, since this church had left its first love, that is, its relationship with God was no longer the same.
In the message to the church of Ephesus in Revelation, He begins by highlighting the work and patience of the church of Ephesus, what it has done to discover the false apostles, which has suffered and has never fainted. Then comes a “but”:
Nevertheless I have somewhat against thee, because thou hast left thy first love.
Revelations 2:4 (KJV)
