There are those who believe we are made up of only soul and body, with the soul somehow containing the spirit. I could argue that point at some length, but for now I prefer to point out a Scripture passage written by Paul, to whom the truth was revealed by the Spirit of Jesus Christ in the desert of Arabia.

May God himself, the God of peace, sanctify you through and through. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ.
1 Thessalonians 5:22-24

With the above passage in mind, let’s look at

Isaiah 53:4-5, which has an interesting sequence that corresponds to my understanding of the sequence of healing for one who is depressed.  In this prophecy of Isaiah, Jesus first took up the infirmities of our body; then He carried the sorrows of our soul; and finally He was crushed for the iniquities of our spirit.  The end of verse 5 says “by his wounds we are healed” – healed body, soul, and spirit.

⁴ Surely he took up our infirmities
    and carried our sorrows,
yet we considered him stricken by God,
    smitten by him, and afflicted.
⁵ But he was pierced for our transgressions,
    he was crushed for our iniquities;
the punishment that brought us peace was upon him,
    and by his wounds we are healed.
