The church's strength doesn't come from its members alone, but from the very power of Christ.
Paul connects the assembly "in the name of the Lord Jesus" with "my spirit" and "the power of our Lord Jesus." He's saying that even though he is physically absent, his spiritual presence, guided by the Holy Spirit, is with them. More importantly, he points to the active, dynamic "power of our Lord Jesus" as the force that should define their gathering and actions. This isn't just about being together; it's about being together empowered by Christ's own spiritual energy to live out His will.
