I receive a daily newsletter from the (in)courage website and in one of them last week, one of the authors was talking about that small voice we all have in our heads, the one that constantly criticizes and belittles us. She added the following scriptures for dealing with those voices.
I knew you before you were born. I created your inner most being. (Psalm 139)
You are my child (1 John 3:1)
I love you with an everlasting love. (Jeremiah 31:3)
You are my workmanship (Ephesians 2:10)
I have redeemed you. (Ephesians 1:7)
You are beautiful (Psalm 45:11)
I chose you, you are mine (Epehsians 1:4, Colossians 3:12, 1 Thessalonians 1:4)
You are no longer a slave. (Galatians 4:7)
You are a new creation. (2 Corinthians 5:17)
So whenever, those voices start whispering to you, look at these verses again, print them off and hang them on your bathroom mirror if you have to, just read them over and over until the voices in your head become more postitive and loving. And the whispering has become God's voice repeating his constant love and admiration for YOU!
