What is the meaning of Acts 26:16-18?

16 But rise, and stand upon thy feet: for I have appeared unto thee for this purpose, to make thee a minister and a witness both of these things which thou hast seen, and of those things in the which I will appear unto thee; 17 Delivering thee from the people, and from the Gentiles, unto whom now I send thee, 18 To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me. (Acts 26:16-18 KJV)

William Burkitt’s Commentary

St. Paul had given King Agrippa an account of his miraculous conversion to Christianity in the former verses; in these he declares to him his extraordinary commission to preach the gospel; that Christ, who appeared to him from heaven, chose him to be a preacher as well as a professor of the gospel, assuring him that he would stand by him, and deliver him from the persecutions of both Jews and Gentiles to whom he should send him. And he would bless Paul’s endeavours to the opening of the eyes of their understanding, and to turn them from darkness to light and from the power of Satan to God so that they might receive, by faith in Christ, remission of sins, and a portion of the heavenly inheritance among those who are regenerated by his Spirit. 

Here note, 1. The honour which God is pleased to put upon the ministry of his word, his own ordinance: the apostle, who was only the instrument, is said to open the eyes of the blind, and turn sinners from darkness to light, and from the power of Satan to God: all these are properly and principally the work of the Spirit of Christ; yet he is pleased to put this honour upon his instruments, the ministers, by whom he works all this, and for which reason they are called co-workers or workers together with Christ.

Note, 2. The apostle’s mission, I send thee. Great is the dignity of gospel ministers, they are God’s messengers; their commission is sealed by the whole Trinity and intimates both their dignity and duty. To intimate their holiness, they are called men of God; for their vigilance, watchmen; for their courage, they are called soldiers; for their painfulness, harvest labourers; for their care of the flock, shepherds: for their wisdom, overseers; for their industry, husbandmen; for their patience, fisherman; for their tenderness, nurses; for their affectionateness, fathers and mothers; for their faithfulness, stewards. A very high and honourable calling; the Son of God despised it not.

Note, 3. St. Paul’s commission in the several branches of it.

1. To open their eyes; that is, to enlighten their understandings, that they may know God and their duty to him: in order to which there is required, 1. Ability in the preachers; how can those who are blind open the eyes of others? Shouldn’t those who are guides and leaders, know the way very well?

2. Perspicuity in the sermon: What hope can there be of opening men’s understandings, when the matter delivered is closed up from them? It was St. Paul’s aim to speak words easily understood, and it should be ours; it is the same thing to preach in an unknown tongue as in an unknown style above the reach of our hearers.

Painted glass is more costly, but plainer glass is clearer and more useful. But we must take care, that though we come in plainness, yet not in rudeness of speech.

The second part of St. Paul’s commission was to turn men from darkness to light and from the power of Satan to God: because of this Paul himself was turned from darkness and the power of Satan. If Paul himself was under the dominion of both, he has little reason to expect that God will honour his ministry for the conversion of others from sin and Satan. The minister’s life is the people’s looking glass, by which they usually dress themselves.

Note, 4. The happy fruit of both St. Paul’s mission and commission. That they may receive forgiveness of sins, and an inheritance among them that are sanctified. Wheresoever true repentance happens by the ministry of the word, there is forgiveness attained, and a title to the inheritance of heaven attained with it.

Note, lastly, A threefold metaphorical description of the sinful state of human nature before conversion, and the like of a state of grace after conversion.

The state of human nature is a state of blindness, To open their eyes.

A state of darkness, To turn them from darkness to light.

A state of slavery, And from the power of Satan unto God.

The state of grace after conversion is set forth by sight, light, and liberty. All this is Christ’s work originally, but his minister’s work instrumentally: I have sent thee to open their eyes, to turn them from darkness to light, and from the power of Satan unto God.
