What is the wisdom behind making the servants of the people of Paradise immortalized youths, young in age, and is the reason for this so that they do not sexually arouse the husband or wife in Paradise?

The wisdom behind making the servants of the people of Paradise youths (wildan) is that this age is more energetic, lighter in service, quicker to respond, and less embarrassing for the one being served. They remain in their youth, freshness, and beauty; they do not age or change. This is further confirmed by the fact that these youths (wildan) are only mentioned in the Quran in conjunction with serving the people of Paradise by going around them. As for the questioner's statement, it is not sound, because Paradise is not a place for sins or temptations; rather, it is a abode of bliss and honor for its inhabitants, where they have whatever they desire.
