'Perfected' in the Bible

And said unto him, Hearest thou what these say? And Jesus saith unto them, Yea; have ye never read, Out of the mouth of babes and sucklings thou hast perfected praise?

And he said unto them, Go ye, and tell that fox, Behold, I cast out devils, and I do cures to day and to morrow, and the third day I shall be perfected.

For by one offering he hath perfected for ever them that are sanctified.

But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.

No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us.
