A symbol never saves, it is a teaching tool to show what god is actually doing,
Circumcision was a symbol. The bible says that was all it was, our spiritual circumcicion was done by the hand of God, baptism is the same water is the symbol, spiritual baptism is what it represents, either way, jesus calls attributing the work of God to the hands or work of men is blasphemy of the HS, so if i was you i would be more worried about commiting the unpardonable sin, that tryint to do anything else
If circumcision and water baptism are just symbols why does the Word indicate otherwise:
Gen 17:14
And the
uncircumcised man child whose flesh of his foreskin is not circumcised,
that soul shall be cut off from his people; he hath broken my covenant.
Moses neglected to circumcise one of his sons and the Lord met Him at the Inn to kill him:
Ex 4:24-26
And it came to pass by the way in the inn, that
the Lord met him, and sought to kill him.
Then
Zipporah took a sharp stone, and cut off the foreskin of her son, and cast it at his feet, and said, Surely a bloody husband art thou to me.
So he let him go: then she said, A bloody husband thou art, because of the circumcision.
The tabernacle laver is a foreshadow of the New Testament water baptism. Moses was told to wash Aaron and his sons as entrance into the priesthood. If they did not wash in the laver before attempting to enter the tabernacle they would DIE:
Ex 29:4
And Aaron and his sons thou shalt bring unto the door of the tabernacle of the congregation, and shalt wash them with water.
Ex 30:20
When they go into the tabernacle of the congregation, they shall wash with water, that
they die not;
These scriptures indicate there were consequences for those who chose not to obey God's commands.
In addition, the unpardonable sin is when someone attributes the casting out of devils to satan's kingdom/fallen angels:
Mark 3:22-30
22And the scribes which came down from Jerusalem said, He hath Beelzebub, and by the prince of the devils casteth he out devils.
23 And he called them unto him, and said unto them in parables, How can Satan cast out Satan?
24 And if a kingdom be divided against itself, that kingdom cannot stand.
25 And if a house be divided against itself, that house cannot stand.
26 And if Satan rise up against himself, and be divided, he cannot stand, but hath an end.
27 No man can enter into a strong man's house, and spoil his goods, except he will first bind the strong man; and then he will spoil his house.
28 Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme:
29 But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation:
30 Because they said, He hath an unclean spirit.
