'Imperfect' in the Bible

If you then, imperfect as you are, know how to give good gifts to your children, how much more will your Father in Heaven give good things to those who ask Him!

For our knowledge is imperfect, and so is our prophesying;

but when the perfect state of things is come, all that is imperfect will be brought to an end.

For the present we see things as if in a mirror, and are puzzled; but then we shall see them face to face. For the present the knowledge I gain is imperfect; but then I shall know fully, even as I am fully known.

Love has in it no element of fear; but perfect love drives away fear, because fear involves pain, and if a man gives way to fear, there is something imperfect in his love.
