I don't think what Mark has said is entirely right.
He means well, and it's a common teaching, but it's not biblical that we are feminine or are to be at all feminine, the Chruch being the bride is symbolic of the level of devotion that Jesus has to the church, it is not like Jesus is marrying individuals and individual men are the "bride". Ever since the Torah, men being effeminate has been considered sin, I don't think that changes in heaven (Deuteronomy 22:5, 1 Corinthians 6:9).. so no, we are to be masculine men, because we are to bear the image of God. and Jesus is a masculine man.
the teaching that Jesus "transcends" Gender is also not biblical and is tainted by the world really. Sure it makes it sound good if He "transcends" gender, that's a positive term right?
But what you're really saying is "Jesus is nonbinary", which is something they say at liberal churches or in the world. It's a perversion.
Everywhere in the bible all 3 persons of God are always referred to as male (even the Holy Spirit, John 14:26, John 15:26)
The person we will interact with most in person, is Jesus, who was born physically as a male.
There are many wrong teachings that I am commonly referred to when it comes to this subject, now the idea of eternal companions is probably wrong too, there's nothing in the bible to support it, so it's just unfounded speculation, but at least it's not based in sin like 2 of these are.
Teaching #1: You personally are married to Christ, and Jesus personally fulfills needs for companionship, sex, etc. They claim that Jesus wants the "one flesh" relationship of a married couple. I hear this from Jonathan Cahn and John Piper and it's revolting, I call it "Gay for Jesus" theology and it's not just wrong, it's blasphemously wrong since it's basically treating it like a homosexual relationship, but hey, it's okay, it's with Jesus! Cahn even aluded to a sex act with Jesus in his description. I've seen Jimmy Evans claim you're personally married to Christ too. The "bride of Christ" teaching of Paul in Ephesians 5 gets twisted into this, Paul was referring to a corporate relationship, not a personal one.
Homosexuality is always sin (1 Corinthians 6:9, Romans 1, Leviticus 20:13). If God had been making marriage to be a picture of your personal relationship with Jesus, it would have been Adam and Steve.
Teaching #2: "Jesus transcends gender so it's not gay to have a one flesh relationship with Jesus" what I call "Trans Jesus" Theology, while they mean "transcends" to make it sound good, they don't get that they're in agreement with the LGBTQ community and their "non binary" Jesus. All scripture has always referred to all 3 persons of the Godhead as male. It is blaspheming to distort the person of God and emasculate them. This one is often connected to teaching #1 to make it seem "not gay" and try to polish out the sin in that first teaching, without realizing it itself is rooted in sin. It is the devil that teaches androgyny, we see evidence for that in our world today.
Teaching #3: That you will simply lose your desires for sex, companionship, etc. This isn't based in sin, it is however, inconsistent with how God has dealt with unfulfilled needs all through history. God has always provided for needs, knowing that fulfilling a need gives satisfaction, and ideally, thankfulness to God for providing those needs. In our sinful state that last part is lacking. I see evidence of this way of dealing with needs continuing in the eternal state as well.
Revelation 21:6
6 And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.
Revelation 22:2
2 In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations.
So, if we thirst, God provides drink, if we have hunger, God provides food, and in our sinless state we will be thankful to the one who provides. It honors Him. Why would He just take away hunger and thirst, so that He doesn't provide, and He is not thanked?
We've all encountered situations where we've "lost our appetite" and has that ever been a good thing that you felt thankful for?
So while it wouldn't be rooted in sin for God to simply take away needs and desires, it wouldn't be a satisfying means of dealing with them, vs providing for them and being thanked and glorified for supplying.
After all, it's what Philippians 4 promises, not that needs would be taken away, but rather that God would supply.
19 But my God shall supply all your need according to his riches in glory by Christ Jesus.
This is consistent with Romans 8:32
32 He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?
This isn't just teaching that your only need becomes Jesus and that by seeing Jesus all your needs are fulfilled because every other need has been taken away.. This is teaching that along with having Jesus.. all things are provided. That God is a lavish giver of gifts and provider.
Revelation 21:7
7 He that overcometh shall inherit all things; and I will be his God, and he shall be my son.
Again, an image that God lavishes those in Christ with everything that they need, not that needs are taken away.
God is a creator. in every instance, He has created the fulfillment of every need we have encountered. It has always been providence, not losing one's appetite, that has brought God praise.
as to what He provides in lieu of marriage to satisfy needs for companionship and love, and desires for sex, I don't know, But that the personal relationship with Him is the fulfillment.. is rooted in sin one way or another, and taking away the need so it doesn't have to be fulfilled does not bring with it praise, so I doubt it.
