Luke 12:29

(de Qu Ev. l. ii. qu. 29.) Now having forbidden all thought about food, he next goes on to warn men not to be puffed up, saying, Neither be ye lifted up, (nolite in sublime tolli μὴ μετεωρίζισθε.) for man first seeks these things to satisfy his wants, but when he is filled, he begins to be puffed up concerning them. This is just as if a wounded man should boast that he had many plasters in his house, whereas it were well for him that he had no wounds, and needed not even one plaster.

For it is sufficient to the prudent for the sake of necessity only, to have a suitable garment, and moderate food, not exceeding what is enough. To the saints it is sufficient even to have those spiritual delights which are in Christ, and the glory that comes after. it were strange for the disciples, who ought to set before others the rule and pattern of life, to fall into those things, which it was their duty to advise men to renounce; and therefore our Lord adds, And seek not what, ye shall eat, &c. Herein also our Lord strongly recommends the study of holy preaching, bidding His disciples to cast away all human cares.

It must however be observed, that He says not, Do not seek or take thought about meat, or drink, or raiment, but what ye shall eat or drink, in which He seems to me to reprove those who, despising the common food and clothing, seek for themselves either more delicate or coarser food and clothing than theirs with whom they live.

Or by being lifted up he means nothing else but an unsteady motion of the mind, meditating first one thing, then another, and jumping from this to that, and imagining lofty things.
