18 There is no fear in love. But perfect love drives out fear, because fear has to do with punishment. The one who fears is not made perfect in love.

Read 1 John 4:18 Using Other Translations

There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love.
There is no fear in love, but perfect love casts out fear. For fear has to do with punishment, and whoever fears has not been perfected in love.
Such love has no fear, because perfect love expels all fear. If we are afraid, it is for fear of punishment, and this shows that we have not fully experienced his perfect love.
