God invites reasoning and conversation, which implies a willingness to communicate, possibly contradicting Jeremiah 29:20's call to hearken without questioning.

Contradiction with Matthew 7:7
Encourages asking and seeking for answers, which could contradict the notion of simply hearkening as stated in Jeremiah 29:20.
Matthew 7:7: Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you:
Contradiction with Proverbs 3:5
Advises trusting in God without relying on understanding, potentially conflicting with the expectation of understanding presented in Jeremiah 29:20.
Proverbs 3:5: Trust in the LORD with all thine heart; and lean not unto thine own understanding.
Contradiction with Psalm 46:10
Calls for stillness and recognition of God, possibly contrasting the active listening or hearkening suggested by Jeremiah 29:20.
