Jesus labels His signs and wonders as "works".

John 5:20 (NIV)
20 For the Father loves the Son, and shows Him all things that He Himself does; and He will show Him greater works than these, that you may marvel.

John 5:36 (NKJV)
36 But I have a greater witness than John's; for the works which the Father has given Me to finish--the very works that I do--bear witness of Me, that the Father has sent Me.
