Ambrose of Milan — as excerpted in the Catena Aurea on Luke 12:27-31

“But He goes on to shew, that neither at the present time, nor hereafter, will grace be lacking to the faithful, if only they who desire heavenly things seek not earthly; for it is unworthy for men to care for meats, who fight for a kingdom. The king knoweth wherewithal he shall support and clothe his own family. Therefore it follows, But seek ye first the kingdom of God, and all these things shall be added unto you.”
