So it comes to be a very important question for us all, how we may not merely be content, as so many of us are, with having scraped inside and just got both feet across the boundary line, but may become great in the kingdom. Let me answer that question in three sentences. The little ones in Christ's kingdom become great by the continual exercise of the same things which admitted them there at first. If greatness depends on position in reference to Jesus Christ, the closer we come to Him and the more we keep ourselves in loving touch and fellowship with Him, the greater in the kingdom we shall be. Again, the little ones in Christ's kingdom become great by self-forgetting service. 'He that will be great among you, let him be your minister.' Self-regard dwarfs a man, self-oblivion magnifies him. If ever you come across, even in the walks of daily life, traces in people of thinking much of themselves, and of living mainly for themselves, down go these men in your estimation at once. Whether you have a beam of the same sort in your own eye or not, you can see the mote in theirs, and you lower your appreciation of them immediately. It is the same in Christ's kingdom, only in an infinitely loftier fashion. There, to become small is to become great. Again, the little ones in Christ's kingdom become great, not only by cleaving close to the Source of all greatness, and deriving thence a higher dignity by the suppression and crucifixion of self-esteem and self-regard, but by continual obedience to their Lord's commandment. As He said on the Sermon on the Mount, 'Whoso shall do and teach one of the least of these commandments shall be called great in the kingdom of heaven.' The higher we are, the more we are bound to punctilious obedience to the smallest injunction. The more we are obedient to the lightest of His commandments, the greater we become. Thus the least in the kingdom may become the greatest there, if only, cleaving close to Christ, he forgets himself, and lives for others, and does the Father's will. III. Lastly, I travel for a moment beyond my text, and note the perfect greatness of all in the perfected kingdom.
