There are many devotionals that can be accessed at bookstores and online.
To know what's right for you, the best start will be the Holy Scriptures, themselves. The world knows them to be "the bible" or "the holy Bible".
Devotionals can be general, for men or women, by age, and even by title (student, husband, single, etc.). There isn't one in particular that Bethel recommends. However, by visiting the bookstore menu option on this site, you will find several available.
Know God and His Word, pray, know yourself and your direction, and choose wisely.
