To wait attentively is to attune ourselves to the signs that what we are waiting for is getting nearer; to recognise those things that delay its coming, and those things that hasten its coming, and to make appropriate response. Too little rain, and the farmer must water the crop; too much sun, and the farmer must erect shade.
Suppose I hope to purchase something that I cannot at present afford to buy. I decide to set aside a certain amount each month towards it. Another, unexpected, expense means that I must revise the time of waiting, longer. An unexpected financial gift means that I can revise the time of waiting, shorter. Whether the day is postponed or brought forward, with each passing day I am closer to that day than when I began to wait.The kingdom of heaven on earth is now, and not yet; the king is imminent in his arrival, and delayed.
