1 John 1:7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
Revelation 1:5 And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,
If the blood of Christ cleanses us from all sin why do we need water?
"How much more shall
the blood of Christ, who through the eternal Spirit offered himself without spot to God,
purge your conscience from dead works to serve the living God? And for this cause he is the mediator of the new testament, that
by means of death, for the redemption of the transgressions that were under the first testament,
they which are called might receive the promise of eternal inheritance. ...
we are sanctified through the offering of the body of Jesus Christ ... for by one offering he hath perfected for ever them that are sanctified. ... Having therefore, brethren, boldness to enter into the holiest
by the blood of Jesus, by a new and living way, which he hath consecrated for us,
through the veil, that is to say, his flesh; and having an high priest over the house of God; let us draw near with a true heart in full assurance of faith, having
our hearts sprinkled from an evil conscience, and our bodies washed with pure water. Let us hold fast the profession of our faith [nb: see the texts of the baptism] without wavering..."
"...Therefore
we are buried with him by baptism into death ... knowing this, that
our old man is crucified with him, that the body of sin might be destroyed."
"For if I build again the things which I destroyed, I make myself a transgressor ... I am crucified with Christ ...
For ye are all the children of God by faith in Christ Jesus. For as many of you as have been baptized into Christ have put on Christ. ... And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise."
"And he received the sign of circumcision, a seal of the righteousness of the faith which he had yet being uncircumcised: that he might be the father of all them that believe, though they be not circumcised;
that righteousness might be imputed unto them also. ... who also walk in the footsteps of that faith of our father Abraham, which he had being yet uncircumcised. For the promise, that he should be the heir of the world, was not to Abraham, or to his seed, through the law, but through the righteousness of faith."
"For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: but he is a Jew, which is one inwardly; and
circumcision is that of the heart..."
"... ye are complete in Him, which is the head of all principality and power:
in whom also ye are circumcised with the circumcision made without hands,
in putting off the body of the sins of the flesh by the circumcision of Christ:
buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead. And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; and having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
"Christ hath redeemed us from the curse of the Law, being made a curse for us: for it is written, 'Cursed is every one that hangeth on a tree:' [we are crucified with Him!] that the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith."
"For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a
new creature."
"If any man be
in Christ,
he is a new creature..."
"But now
in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ. For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us; having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make
in himself of twain one new man, so making peace; and that he might reconcile both unto God
in one body by the cross, having slain the enmity thereby: and came and preached peace to you which were afar off, and to them that were nigh. For through him we both have access by one Spirit unto the Father."
"... God our Father ... having predestinated us
unto the adoption of children by Jesus Christ unto himself [nb above: ye are the children of God by faith in Christ Jesus. For as many as have been baptized into Christ have put on Christ -- that is, have put on that one new man]...
in whom we have redemption
through his blood, the forgiveness of sins ... that ... he might
gather together in one all things
in Christ ... in whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation:
in whom also after that ye believed,
ye were sealed with that holy Spirit of promise ..."
