Ephesians 4:25

25 Therefore, rejecting all falsity and being done now with it, let everyone express the truth with his neighbor, for we are all parts of one body and members one of another.

Look at what our Father tells us: that we are all members of one another. Now many Christians will limit that to, we are only one if we are saved. But is that true? Did our Father create all men and then separate the vast majority from being one with Him?

And this is the will of Him Who sent Me, that I should not lose any of all that He has given Me, but that I should give new life and raise [them all] up at the last day. John 6:39

So the question is how many has Jesus been given?

[Just as] You have granted Him power and authority over all flesh (all humankind), [now glorify Him] so that He may give eternal life to all whom You have given Him. John 17:2

For it was in Him that all things were created, in heaven and on earth, things seen and things unseen, whether thrones, dominions, rulers, or authorities; all things were created and exist through Him [by His service, intervention] and in and for Him. Colossians 1:16

All things have been given over into My power by My Father; and no one knows Who the Son is except the Father, or Who the Father is except the Son and anyone to whom the Son may choose to reveal and make Him known. Luke 10:22

We can clearly see that our Father has given all things to our Husband, our Lord, our Head, and our Savior, Jesus. All flesh is Jesus’. All mankind is Jesus’ All men exist by Him, for Him, and through Him. Jesus will not loose any that He has been given and He has been given all! We are all part of one body. There are those of us who have been empowered to know this and there are those of us who have not been empowered to know this, yet all of us are one body.

This is why the parable of the Marriage Supper of the Lamb is so great. Jesus just plainly tells us that all, both good and bad, will spend eternity with Him.

And those servants went out on the crossroads and got together as many as they found, both bad and good, so [the room in which] the wedding feast [was held] was filled with guests. Matthew 22:10

Not everyone has been chosen to be the Bride of Christ, only a few of us have. But that does not exclude all of the others that Jesus has been given to spend eternity with us. Eternity is filled with guests, just as with a Wedding. A Bride is not a guest at her own wedding, but the Bride does plan and take care of all of her guests. That is what we will do for eternity, take care of our guests, both the good and the bad ones. 

And You have made them a kingdom (royal race) and priests to our God, and they shall reign [as kings] over the earth! Revelation 5:10

Think of Israel, there were twelve tribes, yet only one priestly tribe. Yet they were still a united country. Think of a church. There are pastors, evangelists, teachers, prophets, and apostles, not all have been called to be in leadership, yet all are part of the church. There are both good and bad people in churches, yet all are part of the church. The same holds true for eternity. Our Father would that all men be saved and through Christ they will, 1 Timothy 2:4. Every knee will bow and every tongue will confess Jesus as Lord, Romans 14:11.
