Contradiction with Proverbs 27:1
This verse warns against boasting about tomorrow, which appears to align with James 4:15's teaching on the uncertainty of future plans, rather than directly contradicting it.
Proverbs 27:1: Boast not thyself of to morrow; for thou knowest not what a day may bring forth. [to...: Heb. to morrow day]
Contradiction with Matthew 6:34
This verse advises not to worry about tomorrow, which could be seen as differing from the reliance on God's will suggested in James 4:15, but it does not explicitly contradict it.
Matthew 6:34: Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day [is] the evil thereof.
Contradiction with Ecclesiastes 8:7
This verse highlights humanity's ignorance of the future, aligning with the James 4:15 theme more than contradicting it.
Ecclesiastes 8:7: For he knoweth not that which shall be: for who can tell him when it shall be? [when...: or, how it shall be?]
Contradiction with Luke 12:19
The rich fool makes confident plans without regard for God's will, offering a narrative context that illustrates the consequence of such thinking rather than a direct contradiction.
Luke 12:19: And I will say to my soul, Soul, thou hast much goods laid up for many years; take thine ease, eat, drink, [and] be merry.
