Mark 4:29 But when the fruit is brought forth, immediately he putteth in the sickle, because the harvest is come.
The farmer knows that when the harvest is ripe, there has to be no delay, otherwise the harvest will overripe and be no good.
The time of spiritual harvest has come. Will you please come over into the field and help us? The fruit is over-ripening, because there are few harvesters. Will this generation of believers rise up and do its part or will this harvest be left to rot?
