Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work. (John 4:34)
But Jesus answered them, My Father worketh hitherto, and I work. (John 5:17)
But I have greater witness than that of John: for the works which the Father hath given me to finish, the same works that I do, bear witness of me, that the Father hath sent me. (John 5:36)
And he saw that there was no man, and wondered that there was no intercessor: therefore his arm brought salvation unto him; and his righteousness, it sustained him. (Isaiah 59:16)
JESUS the Son of God (God made visible for the purpose of these five works) is the working ARM of God to do what He, the Spirit (the Father) could not do.
