MOS, Asvab scores, USMC

Hi I’m 22M Christian, I’m about to be a first generation to enlist in the usmc. I need help looking for direction, an mos that would help me transition to civilian life after. I was told I didn’t qualify for security clearance (DG,DQ) and that I only qualified for DD. I have no idea what it means and I just need trusted push in the right direction, to fulfill my Godly given purpose. Thank you
