And with great power - See Acts 1:8. The word “power” here denotes “efficacy,” and means that they had “ability” given them to bear witness of the resurrection of the Saviour. it refers, therefore, I rather to their preaching than to their miracles.
Gave the apostles witness - The apostles bore testimony to.
The resurrection of the Lord Jesus - This was the main point to be established. If it proved that the Lord Jesus came to life again after having been put to death, it established all that he taught, and was a demonstration that he was sent from God. They exerted, therefore, all their powers to prove this, and their success was such as might have been expected. Multitudes were converted to the Christian faith.
And great grace ... - The word “grace” means “favor.” See the notes on John 1:16. The expression here may mean either that the favor of God was remarkably shown to them, or that they had great favor in the sight of the people. It does not refer, as the expression now does commonly, to the internal blessings of religion on a man’s own soul, to their personal advancement in the Christian graces, but to the favor or success that attended their preaching. The meaning probably is, that the “favor” of the “people” toward them was great, or that great success attended their ministry among them. Thus, the same word grace (Greek) is used in Acts 2:47. If this is its meaning, then here is an instance of the power of the testimony of the resurrection of the Lord Jesus to impress the minds of people. But this is not all, nor probably is it the main idea. It is that their union, their benevolence their liberality in supplying the needs of the needy, was a means of opening the hearts of the people, and of winning them to the Saviour. If we wish to incline others to our opinions, nothing is better adapted to it than to show them kindness, and even to minister to their temporal needs.
Benevolence toward them softens the heart, and inclines them to listen to us. It disarms their prejudices, and disposes them to the exercise of the mild and amiable feelings of religion. Hence, our Saviour was engaged in healing the diseases and supplying the needs of the people. He drew around him the poor, the needy, and the diseased, and supplied their necessities, and thus prepared them to receive his message of truth. Thus, God is love, and is constantly doing good, that his goodness may lead people to repentance, Romans 2:4. And hence, no persons have better opportunities to spread the true sentiments of religion, or are clothed with higher responsibilites, than those who have it in their power to do good, or than those who are habitually engaged in bestowing favors. Thus, physicians have access to the hearts of people which other persons have not. Thus, parents have an easy access to the minds of children. for they are constantly doing them good. And thus Sunday-school teachers, whose whole work is a work of benevolence, have direct and most efficient access to the hearts of the children committed to their care.
