Of course, you can volunteer in any number of ways. Some churches will have more volunteer opportunities. And, you may not feel like it if you’re so busy helping as the spiritual leader in your home as it is. That can certainly be your mission field, and you should be in church being spiritually fed at some point during the week.
However, this can also mean sacrificing just to cook a meal once in a while, or visit an elderly person. It can mean spending time to shop – even if it’s just for one item – to donate to a food pantry. You may not have much, but when a widow put only a small offering in at the temple, Jesus said she’d put in more than a rich man who gave a lot. Her gift meant a lot more to the Lord because she’d given out of what little she had.
That was just like the Shunammite woman centuries earlier.
