The Church with Little Strength but Keeping God's Word
Pastor Tan Thai · Mar 8, 2020
This sermon examines the letter to the Church of Philadelphia in Revelation 3, highlighting the contrast between human standards of evaluation and God's standards. Though a small and weak church, Philadelphia is commended by Christ for faithfully keeping His word and not denying His name. The sermon calls every believer to faithfully enter the door of service that Christ Himself has opened.
The sermon opens with an overview of the seven letters to the churches of Asia Minor in the book of Revelation, emphasizing the striking contrast between how God evaluates a church and how people evaluate one. The only two churches that receive pure commendation with no rebuke are Smyrna and Philadelphia — yet these are the two churches that appear weakest and most insignificant by human standards. This forces every reader to ask: by whose standards are we measuring a church or a believer's life?
The central section focuses on the title Christ uses to introduce Himself: the Holy One, the True One, and the One who holds the key of David. The image of the key of David is drawn from Isaiah 22:20-22, describing the palace steward Eliakim, who was granted absolute authority by King Hezekiah over who could enter or leave the royal palace. Eliakim was the shadow; Jesus Christ is the reality — He holds absolute authority to open and shut doors that no power in heaven or on earth can reverse.
The door Christ opens for Philadelphia carries two meanings: the door of salvation (John 10:9) and the door of opportunity for service and sharing the Gospel. The sermon draws on multiple New Testament passages showing that an open door represents missionary opportunity — Paul's ministry in Ephesus (1 Corinthians 16:8-9), in Troas (2 Corinthians 2:12), and his prayer request in Colossians 4:3. The condition for Christ to open this door is not talent, education, or social influence, but faithful obedience to His word and not denying His name.
The sermon also warns that entering the door Christ opens does not guarantee smooth or easy progress. Trials, difficulties, and even failure are inseparable parts of genuine service. Even Christ's own life was filled with hardship and shame by worldly standards, yet it was perfectly aligned with God's will. The pastor emphasizes that through the process of service, God intends not only to produce outward results but to transform the inner spiritual life and character of those who serve.
The application section calls the congregation to recognize that God has placed them in their current city as an open door to bring the Gospel to their fellow Vietnamese. Rather than comparing themselves to other churches or envying other opportunities, every believer is urged to obey, prepare, and serve wholeheartedly when God opens a door. The example of King David in 1 Chronicles 28 is held up as a model: though God did not permit David to build the temple himself, he poured all his energy into meticulous preparation so that Solomon could carry the work forward.
