This command supplies us with an easily applied and effective test. Is there any place where you cannot take it, any act which you feel it would be impossible to do for His sake? Avoid such. Where the safety-lamp burns blue and goes out, is no place for you.
It is a beautiful thought that Jesus does for us what we are thus commanded to do for Him. The high priest bore the names of the tribes on his shoulders and in his heart. 'I have graven thee on the palms of my hands.' We bear Him in our hands and in our hearts. 'I bear in my body the marks of the Lord Jesus.'
III. The great deliverance is to be ever on our lips.
The three regions here named are the inward thought, the outward practice, and the testimony of the lips. Note that that testimony is a consequence of thought and practice.
1. The purpose of the deliverance is to make 'prophets of His law.' Such was the divine intention as to Israel. Such is God's purpose as to all Christians. The very meaning of redemption is there. He has 'opened our lips' that we 'should show forth His praise.' He has regard to 'His own name.' He desires to make us vocal, for the same purpose for which a man strings a harp, to bring sweet music out of it. Words of testimony are a form of love.
2. The other two are incomplete without this vocal testimony.
3. The utterance of the lips, to be worth anything, must rest on and follow the other two. How noble, then, and blessed, how strong and calm and simple our lives would be, if we had this for the one great object of our thoughts, of our practical endeavour, of our words, if all our being was sustained, impelled, made vocal, by one thought, one love!
O my brother, see to it that you give yourself to Him. That great Light will gladden your eyes, will guide your activity, and, like the sunrise striking Memnon's voiceless, stony lips, will bring music. Thought will have one boundless home of 'many mansions.' Work will have one law, one motive, its consecration and strength; and as in some solemn procession, all our steps and all our movements will keep time to the music of our praise to 'Him who loved us.'
