When we do anything of spiritual value, God is the original source of it.
James 3:13 Who is a wise man and endued with knowledge among you? let him shew out of a good conversation his works with meekness of wisdom. 14 But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth. 15 This wisdom descendeth not from above, but is earthly, sensual, devilish. 16 For where envying and strife is, there is confusion and every evil work. 17 But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy.
Wisdom that originates in sinful people has no spiritual value. The wisdom God gives is immeasurably valuable.
