It is very likely that Simon is not a true believer.  The verb "believed" in verse 13 refers more to a mere mental assent that is based on signs and wonders than a genuine saving faith.  Simon's selfish interest in the display of miraculous power is an indication of his unregenerated heart.  His perversion is demonstrated when he offers money in exchange for divine endowment.  Peter points out that Simon has no part or lot with regard to the gift of God.  His heart is not right.  The words "perish" and "repent" are strong words which apply to unbelievers.  The expressions "gall of bitterness" and "bond of iniquity" are better descriptions of a lost man rather than one who is saved.
