Contradiction with Matthew 7:7
Zechariah 7:13 mentions that God will not listen when they call, whereas Matthew 7:7 encourages asking, seeking, and knocking with the promise of receiving, finding, and opening.
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 Psalm 34:17
While Zechariah 7:13 indicates a time when God will not hear, Psalm 34:17 assures that the righteous cry, and the Lord hears and delivers them.
Psalm 34:17: [The righteous] cry, and the LORD heareth, and delivereth them out of all their troubles.
Contradiction with 1 John 5:14
Zechariah 7:13 reflects on God's refusal to listen due to their disobedience, whereas 1 John 5:14 promises that if we ask anything according to His will, He hears us.
1 John 5:14: And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us: [in: or, concerning]
Contradiction with Isaiah 65:24
Opposite to Zechariah 7:13, where God does not listen, Isaiah 65:24 promises that before they call, God will answer and hear while they are still speaking.
Isaiah 65:24: And it shall come to pass, that before they call, I will answer; and while they are yet speaking, I will hear.
Contradiction with James 4:3
Zechariah 7:13 suggests a lack of response from God, but James 4:3 explains it by mentioning not receiving because of asking with wrong motives, suggesting that proper asking would result in receiving.
James 4:3: Ye ask, and receive not, because ye ask amiss, that ye may consume [it] upon your lusts. [lusts: or, pleasures]
Paradox #1
Zechariah 7:13 suggests that when people did not listen to God, He did not listen to them. The potential moral conflict here could be the idea of God's unconditional love and forgiveness versus the idea of God turning away from people as a consequence of their actions. This might seem inconsistent with the belief that God is always ready to forgive and listen, regardless of past behavior.
