Contradiction with Matthew 7:21
While Isaiah 48:2 talks about people who call themselves by God's name, Matthew 7:21 highlights that merely calling on the Lord's name is not enough without doing God's will.
Matthew 7:21: Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Contradiction with Matthew 15:8
Isaiah 48:2 mentions people who identify with God, whereas Matthew 15:8 emphasizes those who honor God with their lips but have hearts far from Him.
Matthew 15:8: This people draweth nigh unto me with their mouth, and honoureth me with [their] lips; but their heart is far from me.
Contradiction with Titus 1:16
Isaiah 48:2 refers to those who invoke God's name, yet Titus 1:16 speaks of those who profess to know God but deny Him by their actions.
Titus 1:16: They profess that they know God; but in works they deny [him], being abominable, and disobedient, and unto every good work reprobate. [reprobate: or, void of judgment]
Contradiction with James 2:14
Isaiah 48:2 discusses claiming to be of God, while James 2:14 challenges faith without actions, suggesting that mere claims are insufficient.
James 2:14: What [doth it] profit, my brethren, though a man say he hath faith, and have not works? can faith save him?
Paradox #1
The potential contradiction or inconsistency with Isaiah 48:2 could relate to the behavior of the people being addressed. They claimed to be from the holy city and relied on the God of Israel, yet their actions did not align with their words. This could reflect a conflict between their professed identity and their actual behavior, highlighting issues of hypocrisy or inconsistency in their faith and actions.
