F.B. Meyer emphasizes the transformative power of being filled with the Holy Spirit, illustrating how one individual can become a powerful conduit for God's grace and strength. He reflects on the life of Elijah, who, despite the overwhelming idolatry of his time, was able to turn the tide back to God through the Spirit's empowerment. Meyer urges believers to seek this filling not for personal gain but for the glory of God, highlighting the necessity of purity and surrender to the Holy Spirit's work. He reassures that this filling is available to all believers, as it was in the early Church, and that it leads to victory over sin, the indwelling of Christ, and empowerment for service. Ultimately, Meyer calls for a renewed commitment to being filled with the Holy Spirit to fulfill God's purpose in the world.
