As if it hadn’t come (Saint Ambrose of Milan)

Is the kingdom of God not eternal then? Jesus says that this is why He was born and came into the world (John 18, 37) and we say: ‘May your kingdom come’, as if it hadn’t already done so. But this wish has another meaning. God comes when we receive His grace. He Himself asserts: ‘The kingdom of God is within you’ (Luke 17, 21).
