Galatians 1:6-9

I am surprised and astonished that you are so quickly [d]turning renegade and deserting Him Who invited and called you by the grace (unmerited favor) of Christ (the Messiah) [and that you are transferring your allegiance] to a different [even an opposition] gospel. Not that there is [or could be] any other [genuine Gospel], but there are [obviously] some who are troubling and disturbing and bewildering you [with a different kind of teaching which they offer as a gospel] and want to pervert and distort the Gospel of Christ (the Messiah) [into something which it absolutely is not]. But even if we or an angel from heaven should preach to you a gospel contrary to and different from that which we preached to you, let him be accursed (anathema, devoted to destruction, doomed to eternal punishment)! As we said before, so I now say again: If anyone is preaching to you a gospel different from or contrary to that which you received [from us], let him be accursed (anathema, devoted to destruction, doomed to eternal punishment)! Galatians 1:6-9

[My precaution was] because of false brethren who had been secretly smuggled in [to the Christian brotherhood]; they had slipped in to spy on our liberty and the freedom which we have in Christ Jesus, that they might again bring us into bondage [under the Law of Moses]. Galatians 2:4

That they all may be one, [just] as You, Father, are in Me and I in You, that they also may be one in Us, so that the world may believe and be convinced that You have sent Me. I have given to them the glory and honor which You have given Me, that they may be one [even] as We are one: I in them and You in Me, in order that they may become one and perfectly united, that the world may know and [definitely] recognize that You sent Me and that You have loved them [even] as You have loved Me. John 17:21-23

But the person who is united to the Lord becomes one spirit with Him. 1 Corinthians 6:17

For this reason a man shall leave his father and his mother and shall be joined to his wife, and the two shall become one flesh. This mystery is very great, but I speak concerning [the relation of] Christ and the church. Ephesians 5:31-32

For we are members of his body, of his flesh, and of his bones. Ephesians 5:30

These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee: John 17:1

For as in one physical body we have many parts (organs, members) and all of these parts do not have the same function or use, So we, numerous as we are, are one body in Christ (the Messiah) and individually we are parts one of another [mutually dependent on one another]. Romans 12:4-5

Little children, you are of God [you belong to Him] and have [already] defeated and overcome them [the agents of the antichrist], because He Who lives in you is greater (mightier) than he who is in the world. 1 John 4:4

For God’s gifts and His call are irrevocable. [He never withdraws them when once they are given, and He does not change His mind about those to whom He gives His grace or to whom He sends His call.] Romans 11:29
