David speaking of his response to his enemies’ false accusations and lies, says in Psalm 38 verses 13 & 14:
13 But I, like a deaf man, do not hear;
And I am like a mute who does not open his mouth.
14 Thus I am like a man who does not hear,
And in whose mouth is no response.
When our enemy Satan falsely accuses us and lies to us we should follow David’s example, be like a deaf man and not hear and be like a mute and not open our mouth. In other words we shouldn’t entertain Satan’s lies and shouldn’t engage his destructive dialogue. His lies and dialogue shouldn’t get that much of our attention. This disarms and disempowers him.
What David says next demonstrates where his focus lay, on God. He says in verse 15:
15 For in You, O Lord, I hope;
You will hear, O Lord my God.
David hoped in God, focused on Him, listened to what He had to say and David talked of God hearing, reflecting that he addressed God, engaged with Him.
When our enemy Satan attacks us with lies whatever form they may take, lets disarm and disempower him, by following David’s example of being deaf and mute to the enemy but listening to and engaging with God.
