A.T. Robertson Commentary James 4:6

"But he giveth more grace. Wherefore [the scripture] saith, God resisteth the proud, but giveth grace to the humble." — James 4:6 (ASV)

More grace (μειζονα χαριν). "Greater grace." Greater than what? "Greater grace in view of the greater requirement" (Ropes), like Ro 5:20f. God does this.

Wherefore (διο). To prove this point James quotes Pr 3:34.

God resisteth the proud (ο θεος υπερηφανοις αντιτασσετα). Present middle (direct) indicative of αντιτασσω, old military term, to range in battle against, with dative case (Romans 13:2) as in 5:6. Hυπερηφανοις (υπερ, φαινομα) is like our vernacular "stuck-folks" (Romans 1:30), "haughty persons."

But giveth grace to the humble (ταπεινοις δε διδωσιν χαριν). Anarthrous adjective again, "to humble or lowly persons," for which word see 1:9f. Cf. 2:5-7; 5:1-6.
