This is a very helpful, short, significant e-book by Glenn Brooke on what fathers should teach their sons. Glenn is an elder at the church my family attended when we lived in the Des Moines, IA area and is an excellent teacher of the Bible.
As a father, I feel the lack of good instruction on parenting that exists right now (with some notable exceptions) — and the difficulty in making time to read the books that are helpful. Glenn’s book helps address both of those issues because it is both short and significant. I’m glad I’ve had the opportunity to read Glenn’s book while my kids are still young!
