In the family of God under the house of the Master Yeshua, therein exists no divisions, denominations or doctrinal differences. Yeshua affirms during his lifetime that his Father was the God of Adam, Abraham, Jacob, Moshe and David! Everyone that espouses and lives by the doctrine of the Covenant under these Patriachs can be considered to be children in the family of God. Yeshua moreover testified that his true mother, brethren and sisters, all his kin are those who seek the will of God.
Who are the children of God?
The children of God are individuals whose souls were created by the Heavenly Father but they have chosen the invitation by the Son of God to become heirs of heavenly glory in the family of God. Those who have not chosen the invitation to live under this Covenant are no less made in the image of God but they do not inherit the promises of the seed of Abraham and Yeshua.
This invitation has come through the Spirit and is received and accepted through the Spirit and through no other way. The designation by no means pertains to any nationality, class, religion, race, community or political affiliation. Being a child of God does not necessarily mean being Christian or Jewish. A child of God can originally have been of any other religion than the Christian or the Jew, any creed, any race. What is more interesting is that there may be many Christians and Jews who may not actually be part of the family of God! So to identify a child of God simply by native origin, birthrights or privileges is erroneous. For God calls everyone through the Spirit yet few respond to His invitation, even the ones who were descendants of the Patriarchs!
Why is it irrelevant to God which creed a person belongs to?
From ancient times, many religions arose to idolize the power of kings and emperors. But from ancient times, the Abrahaminic covenant has been acknowledged and observed by the most faithful. During Yeshua's time, there arose different beliefs surrounding this Covenant. But Yeshua validated man's ancient covenant with God without the need to defer to, identify with or pay lip service with any creed. This was so even for the Jewish creeds from which many claims arose that purported them as 'chosen'.
But the rabbinical caste with 'clout' or 'power' often argued against and detracted from many populations of believers of the ancient histories purporting that the only path to God was through obeisance to the priesthood. This couldn't be further from the truth.
This deceptive authoritarianism in religion, this evil is evident today within the framework of the Christian narrative just as it was then for the Jews. That is exactly why within the Christian body it is difficult to discern who can be righteous and in fact the body of Christ is under grave danger of siding with the enemy. For Yeshua never intended such disunity within the body of his followers.
In fact, there are MANY Christian denominations. They all are vying for the same influence, many in varied degrees of subtle coercion and strategy. God never intended freedoms or religion to dominate the soul. Yet equally all Christian clergy has almost all but lost the true meaning in that they all should be working for the same harvest: the harvest of souls but instead they are working to govern our moral code.
