It is truly a delight to watch profoundly depressed people leave their depression behind as they utilize God's simple healing remedies – adequate rest, plenty of water, sunlight, exercise, healthy plant-based nutrition, etc. There is, however, another essential component for this healing to take place. You see, our thoughts are the source of our emotions or feelings which in turn affect our actions. Though I may be experiencing the most depressing of situations, if my thoughts are continually focused on those negative, oppressive themes, not only will that solve nothing, but feelings of depression will be an inevitable result. Consider this Biblical therapy.
"Why art thou cast down, O my soul? and why art thou disquieted within me? hope thou in God: for I shall yet praise him, who is the health of my countenance, and my God" Psalm 42:11. So, when feeling "cast down", instead of giving into those feelings, choose to joy in our God Who is the Source of hope and health.
Paul provides various counsels regarding control of our thoughts. Colossians 3:2 states "Set your affection on things above, not on things on the earth." The word "affection" is better translated "mind". We must intentionally make the choice to shove negative thoughts out replacing them with positive, uplifting thoughts based on the reality of God's love and promises. That is what it means to set the mind on things above. God will not force our will, but when we make a right choice, He will always strengthen us to follow through.
Here is another great reference. "(For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;)Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ" 2 Corinthians 10:4, 5. If you are one who battles depression, you likely can relate to seeing it as warfare. You can be armed for victory as you give all your negative thinking to Christ. Here is the Biblical replacement for those dreary thoughts. "Whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things" Philippians 4:8.
Praise the Lord for His healing remedies!
