Matthew Henry on Acts 23:25-35

God has instruments for every work. The natural abilities and moral virtues of the heathens often have been employed to protect his persecuted servants. Even the men of the world can discern between the conscientious conduct of upright believers, and the zeal of false professors, though they disregard or understand not their doctrinal principles. All hearts are in God's hand, and those are blessed who put their trust in him, and commit their ways unto him.
