There is no fear in love, but perfect love drives out fear, because fear has to do with punishment. ¹  The ²  one who fears punishment ³  has not been perfected in love.

Dear friends, if our conscience does not condemn us, we have confidence in the presence of God,

And now, little children, remain ¹  in him, ²  so that when ³  he appears we may have confidence and not shrink away from him in shame when he comes back. ⁴ 

By this ¹  love is perfected with ²  us, so that we may have confidence in the day of judgment, because just as Jesus ³  is, so also are we in this world.
