You gave your good Spirit to instruct them and did not withhold your manna from their mouth and gave them water for their thirst. Forty years You sustained them in the wilderness, and they lacked nothing. Their clothes did not wear out and their feet did not swell. Neh 9:20-21 ESV

When the Israelites came out of Egypt, the Lord gave them His Spirit to teach them, provided them food, water, and sustained them. For forty years they lacked nothing, their clothes did not wear out, and there were no diseases among them.

I had a very good friend that used the same disposable razor for years because it never wore out. It was an unusual but very practical gift from the Lord. When it started to lose its edge she would just pray over it and continue. She continued to use it until she passed away twenty-three years later, and it never once nicked her.

The mighty hand of God is able to sustain you. He can give you everything that you need in this life, and in the life to come. Just ask Him. His Spirit can teach you what you need to know, and sometimes the things that you already have may just last longer.
