#156 Of Gentiles Exodus 12

43 And the Lord said unto Moses and Aaron, This is the ordinance of the passover: There shall no stranger eat thereof:

44 But every man's servant that is bought for money, when thou hast circumcised him, then shall he eat thereof.

45 A foreigner and an hired servant shall not eat thereof.

46 In one house shall it be eaten; thou shalt not carry forth ought of the flesh abroad out of the house; neither shall ye break a bone thereof.

47 All the congregation of Israel shall keep it.

48 and when a stranger shall sojourn with thee, and will keep the passover to the Lord, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof.

49 One law shall be to him that is homeborn, and unto the stranger that sojourneth among you.

50 Thus did all the children of Israel; as the Lord commanded Moses and Aaron, so did they.

51 And it came to pass the selfsame day, that the Lord did bring the children of Israel out of the land of Egypt by their armies. Exodus 12: 43-51

It is not a mere token ritual, this is not membership to a club. A stranger may not for cultural experience, curiosity or by any other means than one, partake of this covenant remembrance. When offered entry by removal of the foreskin, a person is forced to consider, and the explanation of a God, Who is the Creator, the fall of man, the covenant with Abraham and the promise of Messiah may not be enough to want to participate. It is often that the ritual becomes the doctrine, in the minds of men that seek a sign or a rite. Some may hold this participation higher than that of a contrite spirit or a mind after God. However harsh or narrow it may seem, it does not exclude, for all men need the same. All are born in sin, all fall short and all need Messiah's sacrifice in order to be reconciled to God. So from the beginning was this way, and none other, from the fall was this problem and none other. Whoever would eat of this Passover, let him eat with the understanding.

But I say, walk by the Spirit, and you will not carry out the desire of the flesh. 17For the flesh sets its desire against the Spirit, and the Spirit against the flesh; for these are in opposition to one another, so that you may not do the things that you please.18But if you are led by the Spirit, you are not under the Law.…Galatians 5:16-18

Thomas said to Him, "Lord, we do not know where You are going, how do we know the way?" 6Jesus said to him, "I am the way, and the truth, and the life; no one comes to the Father but through Me. 7"If you had known Me, you would have known My Father also; from now on you know Him, and have seen Him."…John 14:5-7
