"Why art thou cast down, O my soul? and why art thou disquieted within me?"
After each time, he told his soul to do this:
"...hope thou in God: for I shall yet praise him, who is the health of my countenance, and my God." (Psalm 42:5,11 & 43:5).
The soul is comprised of one's mind, will, and emotions. David found it nessary and helpful to talk to his own soul and to encourage himself.
Today I found myself with a soul that was "cast down" and I had to tell it:
"God is our refuge and strength, a very present help in trouble"(psalm 46:1).
"...God has said, Never will I leave you; never will I forsake you."(Hebrews 13:5)
"...and with his stripes we are healed..."(Isaiah 53:4).
"Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us..."(Ephesians 3:20).
When was the last time you gave your soul a good talking-to? What have you been saying to it?
