The devil is the father of lies - John 8:44
Do not expect the truth from the devil. He can only lie. And he lies unrestrained to harm you.

“… He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies.” (Jesus in John 8:44; NIV)

God is your friend. And the devil is your enemy. He has no more power over you (Luke 10:19), but he is constantly trying to put negative thoughts in your mind. Don’t pick up such thoughts. Instead, think of the loving thoughts that God has over you.
