Thought # 2 on Depression and Biblical solutions
One source, but not the only source, of depression is anxiety. Proverbs 12:25
25 Anxiety in a man's heart weighs it down, But a good word makes it glad.
Anxiety weighs down / depresses you. Since anxiety is one source of depression then preventing anxiety is one way to prevent depression. Peace can prevent you from being weighed down and getting depressed. Lets look at just two ways to sustain peace.
1. Obeying God brings peace. Psalm 119:165
165 Those who love Your law have great peace, And nothing causes them to stumble.
2. Prayer brings peace. Philippians 4:6-7
6 Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.
7 And the peace of God, which surpasses all comprehension, will guard your hearts and your minds in Christ Jesus.
Please don't interpret anything I share as a substitute for Christian counseling and God given wisdom for medicines.
