Said with a loud voice, Stand upright on thy feet. And he leaped and walked.

People's New Testament

14:9,10 The same heard Paul speak. He might have been carried by his friends to the place of speaking, some open square or thoroughfare, to gratify his curiosity, or even to ask alms.

He had faith to be healed. Wrought by hearing the word. As faith is a gospel requisite that we should be healed of our sins, so it was required as a condition of miraculous healing of bodily diseases. Note that this miracle, like those of Christ, is a parable of redemption. There is (1) Hearing of the Word; (2) faith which comes by hearing (Ro 10:17); (3) the command that calls for an exercise of faith; (4) the effort to obey in faith; (5) salvation from the infirmity by obedience. As Christ so often said, so might Paul, Thy faith hath saved thee (Lu 7:50 18:42).

Matthew Henry's Concise Commentary

14:8-18 All things are possible to those that believe. When we have faith, that most precious gift of God, we shall be delivered from the spiritual helplessness in which we were born, and from the dominion of sinful habits since formed; we shall be made able to stand upright and walk cheerfully in the ways of the Lord. When Christ, the Son of God, appeared in the likeness of men, and did many miracles, men were so far from doing sacrifice to him, that they made him a sacrifice to their pride and malice; but Paul and Barnabas, upon their working one miracle, were treated as gods. The same power of the god of this world, which closes the carnal mind against truth, makes errors and mistakes find easy admission. We do not learn that they rent their clothes when the people spake of stoning them; but when they spake of worshipping them; they could not bear it, being more concerned for God's honour than their own. God's truth needs not the services of man's falsehood. The servants of God might easily obtain undue honours if they would wink at men's errors and vices; but they must dread and detest such respect more than any reproach. When the apostles preached to the Jews, who hated idolatry, they had only to preach the grace of God in Christ; but when they had to do with the Gentiles, they must set right their mistakes in natural religion. Compare their conduct and declaration with the false opinions of those who think the worship of a God, under any name, or in any manner, is equally acceptable to the Lord Almighty. The most powerful arguments, the most earnest and affectionate addresses, even with miracles, are scarcely enough to keep men from absurdities and abominations; much less can they, without special grace, turn the hearts of sinners to God and to holiness.
