Romans 8:5

A power or influence, the character, manifestations, or results of which are more peculiarly defined by qualifying genitives. Thus spirit of meekness, faith, power, wisdom. Romans 8:2; Romans 8:15; 1 Corinthians 4:21; 2 Corinthians 4:13; Galatians 6:1; Ephesians 1:17; 2 Timothy 1:7, etc.

These combinations with the genitives are not mere periphrases for a faculty or disposition of man. By the spirit of meekness or wisdom, for instance, is not meant merely a meek or wise spirit; but that meekness, wisdom, power, etc., are gifts of the Spirit of God. This usage is according to Old Testament analogy. Compare Exodus 28:3; Exodus 31:3; Exodus 35:31; Isaiah 11:2.
