I believe there can be coincidences, but I typically don’t trust them… especially in your case.
The Lord led me into the Marine Corps back in '95-99. It was a great experience and there was a lot of times I hated it, but thinking back I was really whining for no reason. The Marine Corps is truly in many ways a spiritual and tradition based institution, but they are also very innovative and progressive when it comes to the warfighting aspect. Most of the other branches outside of SOF units aren’t except maybe in getting new technological implements. Not tactics, or weaponry. We had a stryker 20 years before the army and it was called an LAV for instance.
I will tell you an opposite type of instance. After getting out of the Marines, I decided to go into the army because the air force wasn’t getting me to my tech school after six months and nothing was on the horizon either. The army said they’d take me right away. Right off the guys at MEPS were giving me grief. They said I wasn’t MOS qualified(in the army I actually had two MOS or jobs because the other branches sent you two two different schools whereas the army only sent their guys to one half of it), tried to say they only had positions for nursing, like I had never done this before and I cant read your ********ing me. My recruiters were straight shooters and then these guys fed me BS. When I was about to swear in I felt a horrible sense of dread which was absolutely realized from my horrible experience in the army. Long story short, Ive come to trust in the signs that are put before me, as if I would have listened to them I would have not been put through so much pain.
If you decide to join I would highly advise you NOT to join the army. They pick up the dregs of society who are just there to mooch of the government. There are certainly great guys there, mostly in SOF units and the combat units(not just infantry, but even guys like engineers and what not) but the average “soldier” doesnt look at his fellow soldier any different than some random guy off the street. It was culture shock to a Marine who believes if he doesnt look out for his fellow Marines he is a piece of ****. Also you can probably ask any of the other branches who is the most professional and they will unbiasedly say Marine Corps. Unfortunately the conventional army is very UNprofessional. But the air force or navy are good options as well. Especially if you are looking for a marketable trade upon coming out, but it seems you don’t need that.
The most important thing I can tell you however is to keep practicing your faith. It slaked off for me especially in the army and somewhat in the Marines. I kind of became more of a Bible Christian in the Marine Corps but of course never renounced Catholicism. I was ignorant but eventually came around thanks to the Grace of HIM.
Pray on it, and pay attention to the signs. They may be subtle, but they are there.
