That is contained, as I tried to show in my introductory remarks, in the earlier part of the verse. Our love is made perfect by dwelling in God, and God in us; in order that we may be thus conformed to Christ's likeness, and so have boldness in that great day. To be like Jesus Christ, what is needed is that we love Him, and that we keep in touch with Him. What is it to abide' in Him? --to direct the continual flow of mind and love and will and practical obedience to Him, to bear Him ever in the secret place of my heart whilst my hands are occupied with daily business, and my feet are running the sometimes rough race that is set before me. Think of Him ever, love Him ever. Let His name be like a perfume breathed through the whole atmosphere of your lives. Keep your wills in the attitude of submission, of acceptance, of indecision when necessary, and of absolute dependence upon Him. Let your outward acts be such as shall not bring a film Of separation between Him and you. When thus our whole being is steeped and drenched with Christ, then it cannot but be that we shall be like Him. Even clouds themselves as suns appear, when the sun pierces them with light.' Abide in Me, and I in you.' You cannot make yourselves like Christ, but you can fasten yourselves to Christ, and He will give you power which shall make you like Him.
But, remember, such abiding is no idle waiting, no passive confidence. It is full of energy, full of suppression, when necessary, of what is contrary to your truest self, and full of strenuous cultivation of that which is in accord with the will of the Father, and with the likeness of the first-born among many brethren.'
Dear friends, lie in the light and you will become light. Abide in Christ, and you will get like Christ; and, being like Him, you will be able to lift up your heads, and rejoice when you front Him on the Throne, and you are at the bar. Then, when you are no more in the world, the likeness will be perfected, because the communion is complete. We shall be like Him, for we shall see Him as He is.'
