Doesn't the Bible say baptism saves us in 1 Peter 3:21?The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:
No. Peter says baptism is a figure or picture of what saves us. So, what does baptism present as a picture of how God saves us? The Bible uses the term "baptizo" meaning dip, plunge or submerge
When the candidate for baptism is plunged under the water, it is a picture of the burial of Christ after his all-sufficient sacrificial death. Raising the candidate from the baptism water is pictorial of the resurrection of Christ where, after he ascended, he sits on the right hand of the Father to make intercession for us.
Peter specifically says that baptism does not "put away the filth of the flesh (our sinfulness) but is the result of a good conscious (the result of repentance, believing with the heart and confessing with the mouth the sacrifice of Jesus on the cross for the individual.) This process of removing the stain of sin and gaining righteousness sufficient to be in the presence of God is all because of or by the resurrection of Jesus.
