Contradiction with Numbers 23:19
Numbers 23:19 states that God does not change His mind, while 1 Chronicles 17:27 implies God's blessings are eternal.
Numbers 23:19: God [is] not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do [it]? or hath he spoken, and shall he not make it good?
Contradiction with James 1:17
James 1:17 describes God as unchanging, which might be seen as contrasting with God's interactive promises in 1 Chronicles 17:27.
James 1:17: Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.
Contradiction with Malachi 3:6
Malachi 3:6 highlights God's unchanging nature, potentially conflicting with the specific and conditional blessing in 1 Chronicles 17:27.
Malachi 3:6: For I [am] the LORD, I change not; therefore ye sons of Jacob are not consumed.
