someone who interferes in other’s lives; a meddler
—Pat is a busybody who always wants to know the latest gossip.

In one of his letters, the Apostle Peter writes that Christians should not be surprised when they suffer because they follow Jesus. Instead, they should see that they are sharing in the difficulties of Christ’s life. But Peter says that not all suffering is because of a godly life:

If you are insulted for the name of Christ, you are blessed, because the Spirit of glory, who is the Spirit of God, rests on you. But let none of you suffer as a murderer or thief or criminal or as a troublemaker [busybody]. But if you suffer as a Christian, do not be ashamed, but glorify God that you bear such a name. (1 Peter 4:14-16)

An older meaning of busy is “prying or meddlesome.”
