Again, youth has mostly a certain keenness of relish for life which vanishes only too soon. There are plenty of our young men and women too, of this day, no doubt, who are as _blasé_ and wearied before they are out of their 'teens as if they were fifty. So much the sadder for them, so much the worse for the social state which breeds such monsters. For monsters they are: there ought to be in youth a sense of fresh wonder undimmed by familiarity, the absence of satiety, a joy in joyful things because they are new as well as gladsome. The poignancy of these early delights cannot long survive. Custom stales them all, and wraps everything in its robe of ashen grey. We get used to what was once so fresh and wonderful, and do not care very much about anything any more. We smile pitying smiles--sadder than any tears--at 'boyish enthusiasm,' and sometimes plume ourselves on having come to 'years which bring the philosophic mind'; and all the while we know that we have lost a great gift, which here can never come back any more.
But what if that eager freshness of delight may yet be ours once again? What if the eternal youth of the heavens means, amongst other things, that _there_ are pleasures which always satisfy but never cloy? What if, in perpetual advance, we find and keep for ever that ever new gladness, which here we vainly seek in perpetual distraction? What if constant new influxes of divine blessedness, and constant new visions of God, keep in constant exercise that sense of wonder, which makes so great a part of the power of youth? What if, after all that we have learned and all that we have received, we still have to say, 'It doth not yet appear what we shall be'? Then, I think, in very profound and blessed sense, heaven would be perpetual youth.
I need not pause to speak of other characteristics of that period of life--such as its enthusiasm, its life by impulse rather than by reason, its buoyant energy and delight in action. All these gifts, so little cared for when possessed, so often misused, so irrevocably gone with a few brief years, so bitterly bewailed, will surely be found again, where God keeps all the treasures that He gives and we let fall. For transient enthusiasm, heaven will give us back a fervour of love like that of the seraphs, that have burned before His throne unconsumed and undecaying for unknown ages. For a life of instinctive impulse, we shall titan receive a life in which impulse is ever parallel with the highest law, and, doing only what we would, we shall do only what we ought. For energy which wanes as the years wax, and delight in action which is soon worn down into mechanical routine of toil, there will be bestowed strength akin to His 'who fainteth not, neither is weary.' All of which maturity and old age robbed us is given back in nobler form. All the limitation and weakness which they brought, the coldness, the monotony, the torpor, the weariness, will drop away. But we shall keep all the precious things which they brought us. None of the calm wisdom, the ripened knowledge, the full-summed experience, the powers of service acquired in life's long apprenticeship, will be taken from us.
All will be changed indeed. All will be cleansed of the impurity which attaches to all. All will be accepted and crowned, not by reason of its goodness, but by reason of Christ's sacrifice, which is the channel of God's mercy. Though in themselves unworthy, and having nothing fit for the heavens, yet the souls that trust in Jesus, the Lord of Life, shall bear into their glory the characters which by His grace they wrought out here on earth, transfigured and perfected, but still the same. And to make up that full-summed completeness, will be given to them at once the perfection of all the various stages through which they passed on earth. The perfect man in the heavens will include the graces of childhood, the energies of youth, the steadfastness of manhood, the calmness of old age; as on some tropical trees, blooming in more fertile soil and quickened by a hotter sun than ours, you may see at once bud, blossom, and fruit--the expectancy of spring, and the maturing promise of summer, and the fulfilled fruition of autumn--hanging together on the unexhausted bough.
