John 10:30 is often used as proof that Jesus is God because Jesus said, “I and the father are one.”
But, if you read the next six verses, you will find Jesus explaining that his enemies were wrong to think that he was claiming to be God.
What Jesus obviously means here is that he is one with the Father in purpose.
An essential truth is that three omnipotent, omniscient, and omnipresent persons must be one in will and purpose.
Jesus also prayed that his disciples should be one just as Jesus and the Father are one.
Obviously, he was not praying that all his disciples should somehow merge into one individual
(see John 17:11 and 22). And when Luke reports that the disciples were all one,
Luke does not mean that they became one single human being, but that they shared a common purpose
although they were separate beings (see Acts 4:32). In terms of essence, Jesus and the Father are two, for Jesus said they are two witnesses
What that proves is that they are two persons.
(John 8:14-18). They have to be two, since one is greater than the other (see John 14:28).
When Jesus prayed to be saved from the cross, he said: “Father, if you are willing, take this cup from me; yet not my will, but yours be done.”
(Luke 22:42).
