Loneliness is the sense that something or someone is missing. It shows our humanity. Feeling lonely is evidence that you are created in the image of a God who is in relationship with Himself.
Jesus came that you and I might live in restored relationship with the Father, so to overcome one of the lies of loneliness, you’ll have to believe the truth that you are created in the image of God, on purpose and for a purpose. He sees you and He loves you. He is with you and for you.
