I have been reading in 1 Thessalonians lately and really enjoyed reading chapter 4. Paul tells them that he had heard that they were walking in such a way that they would please God but then he says :"Excel still more!" And then later in that chapter in verses 9&10 he says "I don't have to tell you to love each other, God taught you that and you are doing it but: Excel still more!" Sometimes it is easy to think "I'm doing all I can do" or just simply feel complacent in the spot we are in but we need to remember this admonition "Excel still more!"
Another verse in that chapter is one of my favorites and it says this "Make it you ambition to lead a quiet life and attend to your own business and work with your hands, just as we commanded you, so that you will behave properly toward outsiders and not be in any need." (verses 11-12) I think this one fits in very well with being a homemaker and living frugally. It is good to simply take care of your family (we don't need to have some flashy career), take care of my own business (we need to take care of our families not have to have somebody else take care of us and also we don't need to be involved in other people's business.) and we need to work with our hands - to be hard workers! If we work hard it is unlikely that we will have pressing needs. Also if we live like that then people who are not christians can look at us and be impressed by the life we are living. I hope that you enjoy this verse too!
