What does it mean to be part of a kingdom established without hands?

Being part of a kingdom established without hands indicates that believers can take confidence in their identity as members of Christ’s spiritual kingdom. It emphasizes that their salvation and identity are rooted in God’s sovereign grace rather than any human action. This kingdom is built solely through the work of the Holy Spirit and the preaching of the Gospel, which calls out God's elect from among the nations, highlighting the reality that true worship and life in this kingdom must align with spiritual truths rather than earthly practices.
