Anything that man creates is technically man-made.
It was God that called Abraham, Moses and Joshua bringing into existence ancient Israel. They were men of God.
Modern Israel was brought into existence by Zionists who are Jew promoters and not God promoters. The fact that they blaspheme Christ Jesus is evidence that Jesus, who is Mighty God, has nothing at all to do with them.
Also, consider the Catholic Church and every Protestant Denomination - all man made - all divisive.
The Holy Spirit of Christ Jesus forms the spiritual Body Of Christ in the unification of all believers by His Spirit and His Truth.
That is the TrueChurch.
