Guarding Your Heart
Proverbs 4:23

23 Above all else, guard your heart,
for everything you do flows from it.

PCDC Commentary

God is three persons
Father, Son, Holy Spirit

You are 3 components
Body: Your physical component
Soul: Your everlasting component
Spirit: Your dynamic character

Guard your heart means shield your spirit.
Your spirit constantly changes.
Insure it changes for the better.
