During the Sunday Evening Service on February 18, 2018, the Pastors' and Church Workers' Devotional Service was offered up with the speaker Senior Pastor Dr. Jaerock Lee.

The devotees numbered 9,477 which included pastors, Levite workers (full-time church workers), elders, senior deaconesses, deacons, deaconesses, junior deacons, junior deaconesses, Esther's association (pastors' wives' group), and the Prayer Devotees' Association. The 43 branch churches in Korea joined including Gwangju, Daejeon, Masan, Busan, Yeosu, Changwon, and Chuncheon.

Dr. Jaerock Lee delivered the message entitled "The Shepherd's Heart" based on Romans 5:7-8.

He started the message with an explanation concerning the heart of the shepherd, which is the heart to take care of souls with the Lord's heart and to expand the kingdom of God with the heart of God. He presented the three ways to achieve this heart: first, it is to give up even one's life for the kingdom of God; second, to consider souls precious; and third, to fulfill one's God-given duties silently with the heart of unworthy slaves.

As an instrument of the Holy Spirit to lead countless souls to salvation at this end time, the devotees made up their minds once again to achieve the shepherd's heart that loves souls with his life and to work faithfully and humbly.
