In the USA, you must be at least 35yrs of age in order to serve as President of the country. The Constitution stipulates as much, because they knew even way back when that a person must be truly mature (not faux, stretched out definition of "mature"), experienced and have a sense of balance.
Not so to become elder in JW lala land. Every time I read somewhere about a young buck in his twenties being counted as an "elder", I shake my head in disbelief. WTF do they think "elder" means? Immediate post-teenager/adolescent? Of course, we're talking about a religion that thinks baptizing 8yr olds is okay, even while most on the inside would deem it unthinkable to give away their 8 year old (or ten, eleven, or even 15yo, for that matter) in marriage at the same time in their young lives.
By contrast, there is no age limit to "anointed". David proves that (1 Samuel 16:10-13).
Another thing in regard to Paul's letters to Timothy: if a person were to take a look back to the historical setting, those letters were just that: letters. The bible itself was merely an unbound, loose collection of scrolls and letters for a few centuries. In fact it wasn't until the third or fourth century (325AD) when the council of Nicaea (https://en.wikipedia.org/wiki/First_Council_of_Nicaea) met and decided what was canon to the "scriptures" and what was not.
JWs put an awful lot of emphasis on some things, claiming bible "scholarship" of some sort, but rarely (as in almost never) do any of the writers/leadership bring up the actual historical context of the world at the time, and who decided what, when, or really by/for whom.
Reason I say this: Paul was a Pharisee (Philippians 3:5) before becoming a christian. Reading his writings from an Old testament-holders point of view (meaning someone who still held various parts of the Mosaic law in high esteem, etc) is very eye opening. None of Paul's rantings about females jibes with how Jesus talked to and treated any women in his day. Also remember that Paul was put to death in 67ad. He didn't even live long enough to see the "generations" teaching of Jesus come to fruition (66ad was the siege; sacking of the ciy happened late in 70ad).
Just a few observations of my own.
