For I will show him ... - This seems to be added to encourage Ananias. He had feared Saul. The Lord now informs him that Saul, hitherto his enemy, would ever after be his friend. He would not merely profess repentance, but would manifest the sincerity of it by encountering trials and reproaches for his sake. The prediction here was fully accomplished, Acts 20:23; 2 Corinthians 11:23-27; 2 Timothy 1:11-12.

How great things he must suffer - Instead of proceeding as a persecutor, and inflicting sufferings on others, I will show him how many things he himself must suffer for preaching that very doctrine which he has been hitherto employed in persecuting. Strange change indeed! And with great show of reason, as with incontrovertible strength of argument, has a noble writer, Lord Lyttleton, adduced the conversion of Saul of Tarsus, and his subsequent conduct, as an irrefragable proof of the truth of Christianity.

Some think that the words, I will show him, etc., refer to a visionary representation, which Christ was immediately to give Saul, of the trials and difficulties which he should have to encounter; as also of that death by which he should seal his testimony to the truth. If so, what a most thorough conviction must Saul have had of the truth of Christianity, cheerfully and deliberately to give up all worldly honors and profits, and go forward in a work which he knew a violent death was to terminate!

For I will show him,.... In vision, and by prophecy, either now, or hereafter; or by facts, as they come upon him:

how great things he must suffer for my name's sake; such as weariness, pain, and watchings, hunger, thirst, fastings, cold, and nakedness, perils on various accounts, and from different quarters, stripes, scourges, imprisonment, shipwreck, stoning, and death, of which he himself gives a detail, 2 Corinthians 11:23 so that Ananias had no reason to be afraid to go to him, and converse with him, and do unto him as he was directed.

How great things (ὅσα)

Rev., more correctly, how many.

For I will {h} shew him how great things he must suffer for my name's sake.

(h) I will plainly show him.

9:16 For I - Do thou as thou art commanded. I will take care of the rest; will show him - In fact, through the whole course of his ministry. How great things he must suffer - So far will he be now from persecuting others.

16. I will show him-(See Ac 20:23, 24; 21:11).

how great things he must suffer for my name-that is, Much he has done against that Name; but now, when I show him what great things he must suffer for that Name, he shall count it his honor and privilege.

9:10-22 A good work was begun in Saul, when he was brought to Christ's feet with those words, Lord, what wilt thou have me to do? And never did Christ leave any who were brought to that. Behold, the proud Pharisee, the unmerciful oppressor, the daring blasphemer, prayeth! And thus it is even now, and with the proud infidel, or the abandoned sinner. What happy tidings are these to all who understand the nature and power of prayer, of such prayer as the humbled sinner presents for the blessings of free salvation! Now he began to pray after another manner than he had done; before, he said his prayers, now, he prayed them. Regenerating grace sets people on praying; you may as well find a living man without breath, as a living Christian without prayer. Yet even eminent disciples, like Ananias, sometimes stagger at the commands of the Lord. But it is the Lord's glory to surpass our scanty expectations, and show that those are vessels of his mercy whom we are apt to consider as objects of his vengeance. The teaching of the Holy Spirit takes away the scales of ignorance and pride from the understanding; then the sinner becomes a new creature, and endeavours to recommend the anointed Saviour, the Son of God, to his former companions.
