Be content. It is amazing how frugal you can be if you will just follow what is commanded in Scripture. Be content in the small things, be content in the large things. Give thanks for all you have been given, realizing that you deserve none of it.
"Therefore I tell you,do not be anxious about your life, what you will eat or what you will drink, nor about your body, what you will put on. Is not life more than food, and the body more than clothing? Look at the birds of the air: they neither sow nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not of more value than they? And which of you by being anxious can add a single hour to his span of life? And why are you anxious about clothing? Consider the lilies of the field, how they grow: they neither toil nor spin, yet I tell you, even Solomon in all his glory was not arrayed like one of these. But if God so clothes the grass of the field, which today is alive and tomorrow is thrown into the oven, will he not much more clothe you, O you of little faith? Therefore do not be anxious, saying, 'What shall we eat?' or 'What shall we drink?' or 'What shall we wear?' For the Gentiles seek after all these things, and your heavenly Father knows that you need them all. But seek first the kingdom of God and his righteousness, and all these things will be added to you. ~ Matthew 6:25-33
Not that I am speaking of being in need, for I have learned in whatever situation I am to be content. ~ Philippians 4:11
Now there is great gain in godliness with contentment, for we brought nothing into the world, and we cannot take anything out of the world. But if we have food and clothing, with these we will be content. But those who desire to be rich fall into temptation, into a snare, into many senseless and harmful desires that plunge people into ruin and destruction. For the love of money is a root of all kinds of evils. It is through this craving that some have wandered away from the faith and pierced themselves with many pangs. But as for you, O man of God, flee these things. Pursue righteousness, godliness, faith, love, steadfastness, gentleness. ~ I Timothy 6:6-11
Keep your life free from love of money, and be content with what you have, for he has said, "I will never leave you nor forsake you." ~ Hebrews 13:5
