NT teaches Unity of the Body
Dispensationalism teaches many subgroups and divisions of believers with much segregation and disunity.
There is a subgroup called: OT Saints
There is a subgroup called: Church Age Saints
There is a subgroup called: Trib-Jews
There is a subgroup called: Trib-Saints
There is a subgroup called: 144-Super Jewish Evangelists
Each of these different groups within Dispensationalism must come to salvation in different ways,. Some of animal sacrifices, some of keep the Laws, some by Grace of Christ, some by doing works, some by overcoming and not dying, some second chance of salvation post-Church Age in Tribulation, some will do restoration animal sacrifices again in millennial, etc... Dispensational provides many classes and subclasses of believers, some inheriting Heaven, some inheriting the Earth, some being the Bride, some being the Guest, some being who knows what.
But the Scriptures teach...
Romans 12:5 "So we, being many, are one body in Christ, and every one members one of another"
1 Corinthians 10:17 "For we being many are one bread, and one body for we are all partakers of that one bread."
1 Corinthians 12:12 "For as the body is one, and hath many members, and all the members of that one body, being many, are one body so also is Christ."
1 Corinthians 12:20-25 "But now are they many members yet but one body. And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you. Nay, much more thoese members of the body, which seem to be more feeble, are necessary. And thoese members of the body, which we think to be less honourable, upon these we bestow more abundant: honour; and our uncomely parts have more than abundant comeliness. For our comely parts have no need: but God hath tempted the body together, having given more abundant honour to that part which lacked. That there should be no schism as the body, but that the members should have the samecare one for another."
Ephesians 2:16 "And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby."
Ephesians 4:4-6 "There is one body, and one Spirit, even as ye are in one hope of your calling; One Lord, one faith, one baptism. One God and Father of all, who is above all, and through all, and in you all.
Colossians 3:15 "And let the peace of God rule in your hearts, to the which also ye are called in one body, and be ye thankful."
Colossians 1:24 "Who now rejoice in my sufferings for you, and fill up that which is behind of the afflictions of Christ in my flesh for his body's sake, which is the church."
Ephesians 2:14-15 "For he is our peace, who hath made both one, and hath broken the middle wall of partition betweent us; Having abolished in his flesh, the enmity, even the law of commandments contained in ordinanaces; for to make in himself of twain one new man, so making peace;"
Ephesians 3L21 "Unto him be glory in the church by Christ Jesus throughout ALL AGES, world without end. Amen."
