James 1:8
5 But if anyone is deficient in wisdom, he should ask God, who gives to all generously and without reprimand, and it will be given to him. 6 But he must ask in faith without doubting, for the one who doubts is like a wave of the sea, blown and tossed around by the wind. 7 For that person must not suppose that he will receive anything from the Lord, 8 since he is a double-minded individual, unstable in all his ways. 9 Now the believer of humble means should take pride in his high position. 10 But the rich person’s pride should be in his humiliation because he will pass away like a wildflower in the meadow. 11 For the sun rises with its heat and dries up the meadow; the petal of the flower falls off and its beauty is lost forever. So also the rich person in the midst of his pursuits will wither away.
Shepherd of Hermas 34:1
1 "Hear now," saith he, "the working of angry temper, how evil it is, and how it subverteth the servants of God by its own working, and how it leadeth them astray from righteousness. But it doth not lead astray them that are full in the faith, nor can it work upon them, because the power of the Lord is with them; but them that are empty and double-minded it leadeth astray. 2 For when it seeth such men in prosperity it insinuates itself into the heart of the man, and for no cause whatever the man or the woman is embittered on account of worldly matters, either about meats, or some triviality, or about some friend, or about giving or receiving, or about follies of this kind. For all these things are foolish and vain and senseless and inexpedient for the servants of God. 3 But long-suffering is great and strong, and has a mighty and vigorous power, and is prosperous in great enlargement, gladsome, exultant, free from care, glorifying the Lord at every season, having no bitterness in itself, remaining always gentle and tranquil. This long-suffering therefore dwelleth with those whose faith is perfect.
Notes and References
"... One of the most frequent phrases in The Shepherd of Hermas is the Greek adjective δἰψυχος (“doublemindedness”). While the adjective occurs nineteen times, its cognate verb διψυχεῑν (“to be doublemindend”) occurs twenty times and the substantive διψυχἰα (“doubleminded”) occurs in as many as sixteen times. Indeed, the number of the occurrences of this term in The Shepherd is staggering, given the fact that the term occurs only ten times in all the other early Christian writings combined up to this time (that is, in Jas 1:8; 4:8, Did. 4.4; Bar. 19.5; 1 Clem. 11.2; 23.2-3, 2 Clem. 11:2; 23.5; 19.2) ... (as Bauchkam notes, “It may be noted that in Vision IV δίψυχος is closer to its meaning in Jas 1,8 and in the prophetic sayings quoted in 1 Clem 23.2 and 2 Clem 11.2 than is usual in Hermas: the danger of becoming doubleminded, i.e. of wavering in faith under the threat of persecution ..."
