The imaginations of one’s heart is not a source of Christian faith, as that which alone comes from hearing God.
Why do the heathen rage, and the people imagine a vain thing?The kings of the earth set themselves, and the rulers take counsel together, against the LORD, and against his anointed, saying,Let us break their bands asunder, and cast away their cords from us.He that sitteth in the heavens shall laugh: the LORD shall have them in derision.Then shall he speak unto them in his wrath, and vex them in his sore displeasure. Psa 2:1-5
The heathen in their anger with a God that they know not of, have no source of faith coming from God. (no faith)
Just the imaginations of a heart which is desperately wicked and beyond repair .Christ gives us a new spirit, new heart, to help us with our anger. He is our anger manager. Don’t let the sun go down on it or it will break the fast and a person will carry it for the rest of the new day
Deuteronomy 32:20 And he said, I will hide my face from them, I will see what their end shall be: for they are a very froward generation, children in whom is "no faith".
