Contradiction with Proverbs 13:18
This verse suggests that poverty and shame come to the one who ignores instruction, contradicting the celebration and honor given to the returning son in Luke 15:22, despite his previous behavior.
Proverbs 13:18: Poverty and shame [shall be to] him that refuseth instruction: but he that regardeth reproof shall be honoured.
Contradiction with Galatians 6:7
This verse states that a person reaps what they sow, which seems to contradict the father's gracious treatment of the son in Luke 15:22 who squandered his inheritance.
Galatians 6:7: Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.
Contradiction with Proverbs 22:29
The focus here is on diligence leading to honor, which contradicts the honor the prodigal son receives upon return in Luke 15:22 without showing diligence.
Proverbs 22:29: Seest thou a man diligent in his business? he shall stand before kings; he shall not stand before mean [men]. [mean...: Heb. obscure men]
Contradiction with 2 Thessalonians 3:10
This verse says those unwilling to work should not eat, which contradicts the treatment of the prodigal son in Luke 15:22 who is celebrated without having earned it.
2 Thessalonians 3:10: For even when we were with you, this we commanded you, that if any would not work, neither should he eat.
