In Galatians 5:19-23, specific lists of works of the flesh and fruit of the Spirit provide concrete examples of what good and bad fruit look like.

James 3:12 uses the same fig-tree and grapevine question — reinforcing that inconsistent fruit reveals an inconsistent heart.

Jude 1:12 calls false teachers 'fruitless trees' — applying the fruit test to identify apostates in the church.

Genesis 1:11 establishes the principle that each tree bears fruit 'according to its kind' — the foundation for Jesus' metaphor.

Genesis 1:12 repeats the creation ordinance — fruit trees yielding seed after their kinds, grounding the botanical analogy.

Matthew 12:33 records Jesus saying the same 'tree known by its fruit' — a parallel teaching in a different context.

Proverbs 20:11 says a child is known by his actions — the same 'by their fruit' principle applied to human conduct.
