1 Peter 3:21
[21]And that water is a picture of baptism, which now saves you, not by removing dirt from your body, but as a response to God from a clean conscience. It is effective because of the resurrection of Jesus Christ.
Here is antitupon in a secular Greek writing - "I am placed opposite something that has gone before"
Antitupon*is used only here and in*Hebrews 9:24-note.
For Christ did not enter a holy place made with hands, a*mere*copy*of the true one, but into heaven itself, now to appear in the presence of God for us (see*note*Hebrews 9:24)
Peter is teaching that the fact that 8 people were in an ark and went through the whole judgment, and yet were unharmed, is analogous to the Christian’s experience in salvation by being in (union with) Christ, identified with Christ our "Ark" of salvation so to speak.
Peter is not teaching (as some twist the Scriptures) that immersion in water by a particular denomination saves you. Peter pictures the waters of baptism as*corresponding to*(prefigured by) the deliverance of Noah’s family by water. Noah and his family's identification with the Ark (by going into the ark when the flood came) is a type of the*believer's identification*with Christ (by grace through face) in which he or she identifies with Christ's finished work on the Cross and in so doing in a manner of speaking that person is now safe within the "Ark", Who is Christ Jesus Himself.
This is message of security in Christ is one that Peter's recipients who were experiencing persecution needed to hear, so that might be stabilized when the waves of affliction came upon them.
to bring me through these waters of death and judgment into new and everlasting life through the resurrection of Jesus my Lord." (See full sermon*What is Baptism & Does it Save?)
NOT THE REMOVAL OF DIRT FROM THE FLESH BUT AN APPEAL TO GOD FOR A GOOD CONSCIENCE THROUGH THE RESURRECTION OF JESUS CHRIST: ou sarkos apothesis rhupou alla suneideseos agathes eperotema eis theon di anastaseos Iesou Christou
Eze 36:25,26;*Zec 13:1;*2Cor 7:1) (Acts 8:37;*Ro 10:9,10;*2Cor 1:12;*1Ti 6:12)
Appeal*(1906) (eperotema*from*epí*= intensifies verb +*erotáo*=, to ask, inquire of, beg of) was a technical term used in making a contract. Here it refers to agreeing to meet certain conditions required by God before being placed into the ark of safety (Christ). Salvation requires the desire to obtain a cleansed conscience from God and a willingness to meet the conditions necessary to obtain it.
The baptism Peter speaks of is not water baptism. The Greek word translated "baptism" is more specifically translated "immerse." Noah didn't experience Christian baptism, but was immersed in judgment though protected by the ark. Noah and his family didn't miss the judgment--they were there--but were preserved through it. That's what happens to believers in Christ. Peter made it especially clear he wasn't talking about Christian baptism when he said, "Not the removal of dirt from the flesh." He wasn't speaking of an earthly ordinance but a spiritual reality, specifically of "an appeal to God for a good conscience--through the resurrection of Jesus Christ".
Conscience*(4893) (suneidesis [word study]*from*sun*= with +*eido*= know) literally means a "knowing with", a co-knowledge with oneself or a being of one's own witness in the sense that one's own conscience "takes the stand" as the chief witness, testifying either to one's innocence or guilt. It describes the witness borne to one's conduct by that faculty by which we apprehend the will of God. The Greek noun*Suneidesis*is the exact counterpart of the Latin*con-science, “a knowing with,” a shared or joint knowledge. It is our awareness of ourselves in all the relationships of life, especially ethical relationships. We have ideas of right and wrong; and when we perceive their truth and claims on us, and will not obey, our souls are at war with themselves and with the law of God*Suneidesis*is that process of thought which distinguishes what it considers morally good or bad, commending the good, condemning the bad, and so prompting to do the former and avoid the latter.
The book of Hebrews clearly teaches that one acquires a*good conscience*by faith and not by works of the flesh.
Hebrews 9:9*(note)*which is a symbol for the present time. Accordingly both gifts and sacrifices are offered which cannot make the worshiper perfect (Complete, accomplish or bring to an end, to the intended goal) in*conscience*(Comment: The old sacrifices were never meant to cleanse from sin but only symbolized cleansing. The conscience was never freed from the feeling of guilt because the guilt itself was never removed. The cleansing was predominantly external. Consequently, the worshiper could not obtain a clear conscience, that derives from a deep, abiding sense of forgiveness. Only the working of the Holy Spirit through the Word of God and the efficacy of the blood of the Messiah could give a good conscience.)
Hebrews 9:14*(note)*how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your*conscience*from dead works (I have never heard of a dead person doing live work—it just can’t be done. Anything that you do to try to earn your salvation is a dead work.) to serve the living God?
Hebrews 10:19*(note)Since therefore, brethren, we have confidence to enter the holy place*by the blood of Jesus,*20 by a new and living way which He inaugurated for us through the veil, that is, His flesh, 21 and since we have a great priest over the house of God, 22 let us draw near with a sincere heart in full assurance of faith, having our hearts sprinkled clean from an evil*conscience*and our bodies washed with pure water. (Comment: In Hebrews we see the only way one can obtain a clean conscience is by having one's heart sprinkled (with the blood of Jesus) representing the blood of the New Covenant in which the unregenerate person is born from above and receives a new heart with a new "good"*conscience)
Baptism is a symbolic picture of the resurrection of Christ as well as our own spiritual renewal.
Peter's point is that just as the Flood immersed in the judgment of God everyone yet some passed through safely, so the final judgment will fall on all, but those who are in Jesus Christ will pass through judgment safely. Being in Christ is like being in the ark: we ride safely through the storms of judgment. Believers go through the death and burial of Christ because of their union with Him, and come out again into the new world of His resurrection.
