Soul is your inner self in relation to the creator. For some the creator might be God, Cosmic, or the term that you can best appreciate.
Spirit is more related to who you are on this plane. For example I often hear people say, “She has a youthful spirit, or He has a spirit depression upon him.”
This isn’t really some deep philosophical truth (yet). At this point it’s just defining terms for when it’s time to get to the deep philosophical stuff.
