"The Kingdom of Heaven" is a key concept in Matthew's gospel, and here in the Sermon on the Mount, where Jesus lays the foundations for his teaching, we see he places it at the very heart of what he has to say. To be a citizen of the Kingdom of Heaven, where Christ is king, we live by different priorities and values. To be 'blessed', or to find 'happiness', we have to turn worldly values on their head. People in society are striving for elusive happiness in all areas, but here Christ says: "Blessed are the poor in spirit for theirs is the Kingdom of Heaven" (v3). To be 'blessed' is not simply 'happy' but about an inner, deep contentment, irrespective of external circumstances and traumas in our lives. Jesus says that the key to unlocking that 'blessing' is to admit our complete reliance on God. When we come to him and say "Lord, I have nothing to give, nothing to bring, I am lost, and I need you", when we recognise who we are before God, then we can unlock that blessing, and receive the untold riches he pours upon us, and we step into the Kingdom of Heaven now and into eternity.
