I especially like this part:
first impulse of a Jehovah’s Witness, of course, is to place Jesus in the category of “all things that came into being” because that’s what their theology dictates. In keeping with the teaching of Arius in the early fourth century, there was a time “when the Word was not.” Jesus was the first created being and everything else was created by Jehovah through Jesus.
But John 1:3 doesn’t allow that option. Look at the wording carefully. John says,
“All things came into being by Him, and apart from Him nothing came into being that has come into being,”
or in the NWT,
“…and apart from him not even one thing came into existence” (emphasis mine).
John says the same thing two different ways for emphasis and clarity: everything that ever came into being owes its existence to Jesus, who caused it all to happen. If Jesus caused all created things to come into existence, then He must have existed before all created things came into existence. Therefore, the Word could not have been created.
In other words, if Jesus created everything that has come into being, and Jesus also came into being (as they contend), then Jesus created Himself. He would have to exist as Creator before He existed as a created thing, which is absurd. Therefore, Jesus can’t be placed in the square labeled, “all things that came into being.”
