Through Christ we are receiving a Kingdom which is unshakable. But what is this Kingdom? In the Gospels Jesus begins to describe something that is mysterious, unknown – but yet it is a Kingdom that we are to be part of. He said, His Kingdom is ‘not of this world’ – it’s true. The Kingdom will not come with observable signs, nor can we say, ‘Here it is!’ or ‘It’s over there!’ Paul says, 1 Thessalonians 5.1ff, “Of the times and the seasons you have no need that I write to you, for you know that the Day of the Lord comes as a thief in the night. For when they say ‘Peace and safety’, sudden destruction shall come on them, as travail on a woman with child, and they shall not escape.” So the final moment of the return of Christ is sudden and unexpected. As Jesus said, there’ll be two in a bed, two in a field – two in a factory – one taken, the other left. That’s how sudden it will be, even for the believer.
