CAP is good for flight training if you are a cadet. If you are a SM (which at 24 you would be) it usually isn't an option officially. Usually there are instructors around somewhere to help you, and technically you can use the CAP aircraft for the price of fuel only, actually getting anywhere you'd need to jump through about 967 hoops and it would take about a year. The bottom line is that you can build up some hours but it will be difficult if not impossible to secure a license via CAP. I was in CAP for several years as a cadet and they paid for me to get through my solo when I was 16 through a National Flight Academy... but again this was as a cadet, not SM.
The more you get involved in CAP, the more you'll feel like you're wasting your time...and you'll feel that if you spent the same amount of time working, making money you could have already paid for it yourself. Generally it's old guys or obnoxious ROTC kids who spend meetings talking about back in '44 fighting the Germans. There are a lot of good stories around most CAP hangars and they do real search and rescue missions and it is good for building some time after you get your license. Don't expect to get a PPL from joining. If you were younger it may have been more of a benefit.

-as a side note if you want to do Christian/medical/that whole jazz, it would be wise to get an A&P... as most places will require that with a commercial.
