I found it interesting that Peter mentions a good conscience earlier, and seems to define or describe it as knowing that your works are pleasing to God, even though others are interpreting your deeds negatively. This happens in India, where Christians do mercy toward the poor, and Hindu nationalists will accuse them of proselytising, buying converts with bribes.
1Pe 3:12 For the eyes of the Lord
are over
the righteous, and his ears
are open unto their prayers: but the face of the Lord
is against them that
do evil.
1Pe 3:13 And who
is he that will harm you,
if ye be followers of that which is good?
1Pe 3:14 But and if ye suffer for righteousness' sake (for
doing righteousness/good), happy
are ye: and be not afraid of their terror, neither be troubled;
1Pe 3:15 But sanctify the Lord God in your hearts: and
be ready always to
give an answer to every man that asks you a reason of the hope that is in you with meekness and fear:
1Pe 3:16 Having a good conscience; that, whereas they speak evil of you, as of evildoers, they may be ashamed that falsely accuse
your good conversation in Christ.
1Pe 3:17 For
it is better, if the will of God be so, that ye suffer
for well doing, than for
evil doing.
And this echoes a previous statement -
1Pe 2:12 Having your behaviour honest among the Gentiles: that, whereas they speak against you as evildoers, they may
by your good works, which they shall behold,
glorify God in the day of visitation.
Peter seems to be concerned that Christians not shy away from behaving in a way that they truly believe in all good conscience is Christ-like, and has God's approval, regardless of how others might misinterpret or mischaracterise the Christian's works.
Noah was the only one who was doing this before the flood, and God saved him and the only seven others who were willing to enter the ark with him, before the rains began to fall and the springs opened up.
Peter seems to characterising water baptism as an appeal to God from a good conscience to receive overcoming divine life through a resurrection like Christ's. This power is received through identifying/joining with Jesus in His death and resurrection., as Noah's family joined him in the ark.
The person who believes in Jesus death and resurrection and sets his mind on God intending to submit to God and the One God has appointed forgiver of sins, judge and Lord, that person is given a clean conscience. They know that they no longer have any sins on their record and know that they are pleasing God by being turned to Him in faith. That person, aware of their own flesh's weakness, appeals earnestly to God to partake of the life of Jesus in order overcome in the present sin, the flesh, the world and the devil. Understanding that he needs to be intimately united with Christ, He joins with Jesus in His death as sin-bearing Saviour: rejecting and sloughing off corruption he has accrued because of obeying sin, the world, the flesh and the devil. And he joins Jesus in His resurrection as Lord: inheriting His resurrection power to overcome sin, the flesh, the world and the devils.
If there is a person who believes that Jesus died for him and rose again, and that person begins to set his mind on God intending to submit to God and the One God has appointed Saviour/forgiver of sins, and Lord, that person will receive a clean conscience by knowing their sins are forgiven, and will keep it clean by obeying Jesus and submitting to baptism in His name.
Someone who believes in Jesus death and resurrection for them in order to merely escape the consequences of their sins, but will not submit to the baptism Jesus commanded, is he really committed to having Jesus as his
Lord? Can a person half-hearted about Jesus'
Lordship, who is evading the baptism He commanded, expect to live in victory over sin, the flesh, the world and devils? He has not united with Jesus as
Lord in His resurrection through baptism, in order to receive the resurrection power. Can someone avoiding the Lord's commanded baptism be making
an earnest request from a good conscience for salvation from the coming destruction of the ungodly who reject God's lordship? and for divine life through a resurrection like Jesus Christs?
1Pe 3:21 ... which flood account
is also an antitype. Baptism is now saving you (from the coming destruction of the ungodly: Just as being in the ark as the waters rose and covered and all, even the ark at times, saved Noah and family, so being in Christ while the waters of baptism cover you, saves you from the coming destruction) - not a removal of dirt from flesh, but rather a good conscience's earnest plea for what is characteristic of God through a resurrection that is characteristic of Jesus Christ.
