If all your strength is going thither, there is none left to grow with. Many professing Christians take such deep draughts of the intoxicating cup of this world's pleasures that it stunts their growth. People sometimes give children gin in order to keep them from growing. Some of you do that for your Christian character by the deep draughts that you take of the Circean cup of this world's pleasures and cares.
And not unfrequently, some one favourite evil, some lust or passion, or weakness, or desire, which you have not the strength to cast out, will kill all aspirations and destroy all possibilities of growth; and will be like an iron band round a little sapling, which will confine it and utterly prevent all expansion. Is that the case with any of us? We all need—and I pray you suffer—the word of exhortation.
III. Now, again, consider the method of growth.
There are two things essential to the growth of animal life. One is food, the other is exercise; and your Christian character will grow by no other means.
Now as to the first. The true means by which we shall grow in Christian grace is by holding continual intercourse and communion with Jesus Christ. It is from Him that all come. He is the Fountain of Life; He gives the life, He nourishes the life, He increases the life. And whilst I have been saying, in an earlier part of this discourse, that we are not to expect an effortless growth, I must here say that we shall very much mistake what Christian progress requires if we suppose that the effort is most profitably directed to the cultivation of specific and single acts of goodness and purity. Our efforts are best when directed to keeping ourselves in union with our Lord. The heart united to Him will certainly be advancing in all things fair and lovely and of good report. Keep yourselves in touch with Christ; and Christ will make you grow. That is to say, occupy heart and mind with Him, let your thoughts go to Him. Do you ever, from morning to night, on a week-day, think about your Master, about His truth, about the principles of His Gospel, about His great love to you? Keep your heart in union with Him, in the midst of the rush and hurry of your daily life. Are your desires turning to Him? Do they go out towards Him and feel after Him? It will take an effort to keep up the union with Him, but without the effort there will be no contact, and without the contact there will be no growth. As soon may you expect a plant, wrenched from the soil and shut out from the sunshine to grow, as expect any Christian progress in the hearts which are disjoined from Jesus Christ. But rooted in that soil, smiled upon by that sun, watered by the perpetual dew from His Heaven, we shall 'grow like the lily, and cast forth our roots like Lebanon. The secret of real Christian progress and the direction in which the effort of Christian progress can most profitably and effectually be made, is simply in keeping close to our Lord and Master. He is the food of the Spirit. 'I am come that they might have life, and that they might have it more abundantly.'
Communion with Christ includes prayer. Desire to grow will help our growth. We tend to become what we long to be. Desire which impels to effort will not be in vain if it likewise impels to prayer. We may have the answer to our petition for growth in set ways; we may be but partially conscious of the answer, nor know that our faces shine when we go among men. But certainly if we pray for what is in such accordance with His will as 'growth in grace' is, we shall have the petition that we desire. That longing to know Him better and to possess more of His grace, like the tendrils of some climbing plant, will always find the support round which it may twine, and by which it may ascend.
The other condition of growth is exercise. Use the grace which you have, and it increases. Practice the truth which you know, and many things will become clearer. The blacksmith's muscles are strengthened by wielding the forge-hammer, but unused they waste. The child grows by exercise. To him that hath—truly possesses with that possession which only use secures—shall be given.
Communion with Christ, including prayer, and exercise are the means of growth.
IV. Lastly, observe the solemn alternative to growth.
It is not a question of either growing or not growing, and there an end; but if you will look at the context you will see that the exhortation of my text comes in in a very significant connection. 'Behold! beware, lest being led away ... ye fall from your own steadfastness.' 'But grow in grace.' That is to say, the only preventive of falling away from steadfastness is continual progress. The alternative of advance is retrogression. There is no standing still upon the inclined plane. If you are not going up, gravity begins to act, and down you go. There must either be continual advance or there will be certain decay and corruption. As soon as growth ceases in this physiology disintegration commences. Just as the graces exercised are strengthened, so the graces unexercised decay. The slothful servant wraps his talent in a napkin, and buries it in the ground. He may try to persuade his Master and himself with 'There Thou hast that is Thine'; but He will not take up what you buried. Rust and verdigris will have done their work upon the coin; the inscription will be obliterated and the image will be marred. You cannot bury your Christian grace in indolence without diminishing it. It will be like a bit of ice wrapped in a cloth and left in the sun, it will all have gone into water when you come to take it out. And the truth that you do not live by, whose relations and large harmonies and controlling power are not being increasingly realised in your lives; that truth is becoming less and less real, more and more shadowy, and ghostlike to you. Truth which is not growing is becoming fossilised. 'The things most surely believed' are often the things which have least power. Unquestioned truth too often lies 'bedridden in the dormitory of the soul side by side with exploded error.' The sure way to reduce your knowledge of Jesus Christ to that inert condition is to neglect increasing it and applying it to your daily life. There are men, in all churches, and there are some whole communions whose creeds are the most orthodox, and also utterly useless, and as near as possible nonentities, simply because the creed is accepted and shelved. If your belief is to be of any use to you, or to be held by you in the face of temptations to abandon it, you must keep it fresh, and oxygenated, so to say, by continual fresh apprehension of it and closer application of it to conduct. As soon as the stream stands, it stagnates; and the very manna from God will breed worms and stink. And Christian truth unpractised by those who hold it, corrupts itself and corrupts them.
