Jhn 4:23, But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.Perhaps you can post the verses and highlight where they clearly state that or explain how, exactly, how they do.
Jhn 4:24, God is a Spirit: and they that worship him must worship him in spirit and in truth.
Here we have the clear teaching that the Father is a Spirit.
Now, below, we will see that the Father dwells in Jesus and Jesus in the Father; which might indicate that the Father is Jesus' Spirit.
Jhn 14:7, If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him.
Jhn 14:8, Philip saith unto him, Lord, shew us the Father, and it sufficeth us.
Jhn 14:9, Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father?
Jhn 14:10, Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.
Jhn 14:11, Believe me that I am in the Father, and the Father in me: or else believe me for the very works' sake.
In the above underlined, we can see that Philip asked Jesus to shew them the Father; and that Jesus responded by pointing to Himself: Have I been so long with you and yet thou hast not known me, Philip? He that hath seen me hath seen the Father.
It should be clear in this passage that Jesus is here claiming to be the Father, in His Spirit. He is not claiming to merely be like the Father. In response to Philip's request to shew them the Father, Jesus' response is that Philip should have known Him by now; that He is the Father come in flesh.
