Apostelgeschichte 1:22

Beginning from the baptism of John--by whom our Lord was not only Himself baptized, but first officially announced and introduced to his own disciples. unto that same day when he was taken up from us, must one be ordained to be a witness with us of his resurrection--How clearly is the primary office of the apostles here expressed: (1) to testify, from personal observation, to the one great fact of "the resurrection of the Lord Jesus"; (2) to show how this glorified His whole previous life, of which they were constant observers, and established His divine claims.

The inspired historian begins his narrative of the Acts of the Apostles, I. With a reference to, and a brief recapitulation of, his gospel, or history of the life of Christ, inscribing this, as he had done that, to his friend Theophilus (Act 1:1, Act 1:2). II. With a summary of the proofs of Christ's resurrection, his conference with his disciples, and the instructions he gave them during the forty days, of his continuance on earth (Act 1:3-5). III. With a particular narrative of Christ's ascension into heaven, his disciples' discourse with him before he ascended, and the angels' discourse with them after he ascended (Act 1:6-11). IV. With a general idea of the embryo of the Christian church, and its state from Christ's ascension to the pouring out of the Spirit (Act 1:12-14). V. With a particular account of the filling up of the vacancy that was made in the sacred college by the death of Judas, by the electing of Matthias in his room (Act 1:15-26).
