Mark, too, the strong expression of the Church's dependence on God. 'Lord' here is an unusual word, and means 'Master,' while the Church collectively is called 'Thy servants,' or properly, 'slaves.' It is a different word from that of 'servant' (rather than 'child') applied to Jesus in verses 27 and 30. God is the Master, we are His 'slaves,' bound to absolute obedience, unconditional submission, belonging to Him, not to ourselves, and therefore having claims on Him for such care as an owner gives to his slaves or his cattle. He will not let them be maltreated nor starved. He will defend them and feed them; but they must serve him by life, and death if need be. Unquestioning submission and unreserved dependence are our duties. Absolute ownership and unshared responsibility for our well-being belong to Him.
Further, the view of Christ's relationship to God is the same as occurs in other of the early chapters of the Acts. The title of 'Thy holy Servant Jesus' dwells on Christ's office, rather than on His nature. Here it puts Him in contrast with David, also called 'Thy servant.' The latter was imperfectly what Jesus was perfectly. His complete realisation of the prophetic picture of the Servant of the Lord in Isaiah is emphasised by the adjective 'holy,' implying complete devotion or separation to the service of God, and unsullied, unlimited moral purity. The uniqueness of His relation in this aspect is expressed by the definite article in the original. He is _the_ Servant, in a sense and measure all His own. He is further _the_ Anointed Messiah. This was the Church's message to Israel and the stay of its own courage, that Jesus was the Christ, the Anointed and perfect Servant of the Lord, who was now in heaven, reigning there. All that this faith involved had not yet become clear to their consciousness, but the Spirit was guiding them step by step into all the truth; and what they saw and heard, not only in the historical facts of which they were the witnesses, but in the teaching of that Spirit, they could not but speak.
The answer came swift as the roll of thunder after lightning. They who ask for courage to do God's will and speak Christ's name have never long to wait for response. The place 'was shaken,' symbol of the effect of faithful witness-bearing, or manifestation of the power which was given in answer to their prayer. 'They were all filled with the Holy Ghost,' who now did not, as before, confer ability to speak with other tongues, but wrought no less worthily in heartening and fitting them to speak 'in their own tongue, wherein they were born,' in bold defiance of unlawful commands.
The statement of the answer repeats the petition verbatim: 'With all boldness they spake the word.' What we desire of spiritual gifts we get, and God moulds His replies so as to remind us of our petitions, and to show by the event that these have reached His ear and guided His giving hand.
