God was so good. I went to pick up my son at work. The van began to get hot, but didn't overheat. After he got in the van, the red warning light went on. He was able to help me get the van home.
The praise is that I was not alone. I was not on I-44, a major highway when it broke down. We were able to get it home and to the repair shop (where we found out it would be at least $2000 to fix it... it's worth less than $1000 and has other issues). It happened on the last day that my son had to work in another town. My Emily is at camp for a month.
My husband will be able to take my Michael to his new job early and drop him off, then pick him up on the way home daily.
Emily and Michael will not require me to give them rides for the month of July. Amy will just have to stay at home with me. Just a week before, I said I wish I were a stay-at-home mother. I didn't know how soon that would happen!
Now, I will believe God for a replacement.
