You should only enter the convent if you have a supernatural calling – a calling from the Lord Himself. It’s not something that you weigh pros and cons for, as if deciding whether to buy a house.
In addition to the vocation, one might consider being a nun because:
– your life centers on Jesus Christ – on glorying, exalting, praising, and blessing Him, constantly – the nun is His bride;
– the monastic lifestyle forces you to confront yourself within a framed setting, which increases opportunities for purification and thus expedites the process of holiness;
– your purpose in life is to pray for the salvation of souls and souls in purgatory, so you do work few others souls do on a regular basis; and
– the monastic life requires many sacrifices, which all contribute to carrying Christ’s cross, and thus contribute to the economy of salvation and expiation.
There are a lot of specifics related to the religious order, for example. Many Carmelites will experience God very intimately, in a form of spiritual marriage – ecstatic prayer, for example. Others, such as Dominicans, shape the whole person, and dedicate their lives to loving Christ via study of His word.
The religious vocation is the highest vocation for a woman.
