1 Peter 3:12 says, 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.  God hears the righteous and watches over them.  On the other hand, God does not hear those who do evil, except for their prayer for forgiveness by faith in Christ.  Verse thirteen asks, And who is he that will harm you, if ye be followers of that which is good?  Matthew Henry says this means under normal conditions, we don't have to fear any harm for doing good, but if we live in a time or place where Christians are persecuted, even then they cannot harm us spiritually.  Verse fourteen declares, But and if ye suffer for righteousness’ sake, happy are ye: and be not afraid of their terror, neither be troubled;  This is a further statement that even when persecuted, we are to be happy in our salvation and not afraid of anything this world can do to us.  This is only true if we are suffering for righteousness sake, and not if we are suffering because we have not lived up to our calling as followers of Christ.  Verse fifteen states, But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:  We are to sanctify ourselves, or put God first in our hearts.  We are also to be ready to tell anyone who asks why we have hope in life, and to do so humbly.  Verse sixteen says, 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.  When we are obedient to God and empowered by the Holy Spirit, we can live with a clear conscience.  If we are accused of doing wrong then, it will be those that falsely accuse us who will ultimately be put to shame.  Verse seventeen adds, For it is better, if the will of God be so, that ye suffer for well doing, than for evil doing.  If we are going to suffer as followers of Christ, it should always be because of doing God's will if we are to be bring honor and glory to Him.  Verse eighteen declares, For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit:  Christ died once for the sins of all mankind.  Jesus Christ was the just dying for the unjust, and He is the only One qualified to do so.  Because of His sacrifice, we must die to the flesh in order to be obedient to God.  Verse nineteen adds, By which also he went and preached unto the spirits in prison;  Christ reached out to those in prison.  I believe that this does not mean physically imprisoned, but imprisoned by sin.  Matthew Henry relates it to those in the days of Noah who would not listen to him.  Verse twenty states, Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water.  We can definitely say that this refers to those in the days of Noah, who after all the years of Noah building the Ark and warning of the coming destruction refused to believe in God's warning.  Only eight were saved.  Verse twenty-one proclaims, 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:  It is not baptism itself that saves us, but the death, burial and resurrection of Christ that it represents that does.  We are to be baptized, when possible, to show our obedience to Christ.  Verse twenty-two proclaims, Who is gone into heaven, and is on the right hand of God; angels and authorities and powers being made subject unto him.  Jesus Christ now sits on the right hand of the heavenly Father, and everything is under His power.  I cannot fully comprehend nor explain the triune nature of God, but simply accept that the Father, Son, and Holy Spirit are One.
