”Even in laughter the heart is sorrowful; and the end of that mirth is heaviness.” ~ Proverbs 14:13
The truth in this verse is seen around us everyday and even in our own lives. People laugh a lot but are never very far from depression. Some people even spend their life searching for constant stimulation to avoid facing the underlying sorrow in their hearts.
However, there is ONLY one cure: The heart of man was made by God and for God. Therefore, lasting joy can be found nowhere else: real joy is only found in the heart yielded to God. Without, God there is only sorrow covered with laughter and heaviness (depression) covered with mirth.
“Be glad in the LORD, and rejoice, ye righteous: and shout for joy, all ye that are upright in heart.” ~ Psalm 32:11
“Thy words were found, and I did eat them; and thy word was unto me the joy and rejoicing of mine heart: for I am called by thy name, O LORD God of hosts.” ~ Jeremiah 15:16
