When you walk into a dark room you don't try to get rid of the darkness BEFORE you turn on the light. That's impossible and a waste of time.
All you need is light. Open the blinds, turn on the lamp, light the candle and the darkness is gone.
So it is with your heart. Do you have a wicked and dark heart?
You'll know by the way you talk.
"out of the abundance of the heart the mouth speaketh." Matt 12:34
You'll know by the way you look.
"A glad heart makes a cheerful face" Prov 15:13
Don't try and get rid of the wickedness and darkness before you turn on the light. It is impossible. Like me, you cannot be kind, or thankful, or forgiving all on your own. You need to turn on the light.
Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life. John 8:12
