In the book of Hebrews, the writer tells us that when we gather together for worship, we come to Mount Zion and the city of the living God, the heavenly Jerusalem (Hebrews 12:22). Now the heavenly Jerusalem is the perfect city under the rule of a perfect King, the kingdom that we are eagerly waiting to receive from God (Hebrews 12:28). That is not where we go when we meet together for worship. But the writer suggests that something of the reality of that heavenly city must be seen when we gather together as God’s church. Something of that city must be evident in our meetings so that when unbelievers join us, they will cry out, Surely God is really among you (1 Corinthians 14:25).
