Very solemnly significant is the difference between _striving_ and _seeking_. It is like the difference between wishing and willing. There may be a seeking which has no real earnestness in it, and is not sufficiently determined, to do what is needful in order to find. Plenty of people would like to possess earthly good, but cannot brace themselves to needful work and sacrifice. Plenty would like to 'go to heaven,' as they understand the phrase, but cannot screw themselves to the surrender of self and the world. Vagrant, halfhearted seeking, such as one sees many examples of, will never win anything, either in this world or in the other. We must strive, and not only seek. That is true, even if we do not look beyond time; but Jesus carries our awed vision onwards to the end of the days, in the expansion of his warning, which follows in verses 25-27. No doubt, the words had a meaning for His hearers in reference to the Messianic kingdom, and a fulfilment in the rejection of the nation. But we have to discern in them a further and future significance. Observe that the scene suggested differs from the similar parable of the virgins waiting for their Lord, in that it does not describe a wedding feast. Here it is a householder already in his house, and, at the close of the day, locking up for the night. Some of his servants have not returned in time, have not come in through the narrow gate, which is now not only narrow, but closed by the master's own hand. The translation of that is that, by a decisive act of Christ's in the future, the time for entrance will he ended. As in reference to each stage of life, specific opportunities are given in it for securing specific results, and these can never be recovered if the stage is past; so mortal life, as a whole, is the time for entrance, and if it is not used for that purpose, entrance is impossible. If the youth will not learn, the man will be ignorant. If the sluggard will not plough because the weather is cold, he will 'beg in harvest.' If we do not strive to enter at the gate, it is vain to seek entrance when the Master's own hand has barred it. The language of our Lord here seems to shut us up to the conclusion that life is the time in which we can gain our entrance. It is no kindness to suggest that perhaps He does not shut the door quite fast. We know, at all events, that it is wide open now.
