Then Peter, turning around, saw the disciple whom Jesus loved following, who also had leaned on His breast at the supper, and said, "Lord, who is the one who betrays You?" Peter, seeing him, said to Jesus, "But Lord, what about this man?" Jesus said to him, "If I will that he remain till I come, what is that to you? You follow Me."
John 21:20-22

“Curiosity killed the cat,” goes the saying that dates back from the 1890s. It is a reminder that while having an inquisitive mind is not a bad thing, not everything we might wish to know is our business to know. This is especially true when it comes to God’s will for other people’s lives.

Peter wanted to know about John’s future. The fact is, we don’t even know about our future, so why would we be overly concerned with another’s future?

We are better off to be concerned with living our lives in the present in ways that will provide the best case scenarios for our future. If we do that, we can rest concerning our futures, knowing that we have been good stewards of the present, trusting in the goodness of God for the future.

When it comes to other people’s future, let us do what we can to help those we are responsible for—our children and grandchildren, for instance. Having done what we can, let us pray for those in whose lives we invest ourselves—and trust God for their futures as well.

And as Jesus said to Peter, the most important thing we can do in any case, is follow Jesus.

Inquisitive minds are not a bad thing. But curiosity killed the cat.
