Genesis 2:7).

CONCLUSION:
Therefore the meaning of
1 Thessalonians 5:23 "body, soul and spirit) is simply that God will sanctify you to the utmost of all your being (body, breath/soul and mind/spirit) and for
Matthew 10:28, do not be afraid of those who can kill the body but cannot take away your life as that comes from God (eternal life). Be afraid therefore of those who can take away your body and your life (eternal life) that comes from God (context is to "believers" -
John 3:36).
Take Care.
