Joy is a lasting inward experience that isn’t affected by the storms of life, while happiness is a momentary feeling that we may experience in good times.

Joy is superior to happiness. Nevertheless, God expects us to live and experience both joy and happiness.
God has placed a great emphasis on joy. He knows that joy is important for our overall wellbeing.
Jesus in His final moments before His death, called the disciples and said to them in me you may have peace but in the world you will have tribulation but be of good cheer I have overcome the world (John 16:33)
Joy is priceless virtue that we should all seek after. Weeping may endure for a night joy cometh in the morning (Psalm 30:5).
When anxiety was great within me, your consolations brought me joy (Psalm 94:19).

Rejoice even when the devil is trying to steal your joy.
The thief cometh to steal, kill and to destroy, I have come that they may have life and that they may have it more abundantly (John 10:10-21).
Anxiety is a by-product of worry, and the devil is the chief architect behind any situation that causes us to worry.
It is no secret that the devil hates us, and he does everything and anything within his power to steal our joy.
But we must fight the good fight of faith and hold on to our joy in God.
Life’s trials may stress you, but you must exercise patience and wait on God.
His grace will sustain you, and His joy will revive your worry and sorrowful soul.
This is the day that the Lord hath made we will rejoice and be glad in it. (Psalm 118:24)
