Acts 8:23

Verse 23. For I perceive. That is, by the act which he had done. His offer had shown a state of mind that was wholly inconsistent with true religion. One single sin may as certainly show that there is no true piety, as many acts of iniquity. It may be so decided, so malignant, so utterly inconsistent with just views, as at once to determine what the character is. The sin of Simon was of this character. Peter here does not appear to have claimed the power of judging the heart; but he judged, as all other men would, by the act. In the gall. This word denotes properly bile, or that bitter, yellowish-green fluid that is secreted in the liver.
