1Pe 3:8, 9  "Finally, all of you, have unity of mind, sympathy, brotherly love, a tender heart, and a humble mind.  Do not repay evil for evil or reviling for reviling, but on the contrary, bless, for to this you were called, that you may obtain a blessing." 

Having the mind of Christ means that with humble and tender compassion and sympathy you understand where each other is coming from. You are family and care for one another like brothers and sisters. In every way you bless each other, talk to one another in a way that brings help and healing. 
If you really want a life that is filled with love, joy and peace, if you want to be happy, pursue the ways of God. His ways are pure and perfect, they lead to life. 
This is because God keeps His eye on those who emulate Him, He listen to the needs of His children. You really don't want to be face to face with Him in His anger against evil. 

1Pe 3:10-12  "For "Whoever desires to love life and see good days, let him keep his tongue from evil and his lips from speaking deceit;  let him turn away from evil and do good; let him seek peace and pursue it." For the eyes of the Lord are on the righteous, and his ears are open to their prayer. But the face of the Lord is against those who do evil." 

Now who would you think can ultimately cause you any lasting pain if you are right with God? 

Rom 8:31  "What then shall we say to these things? If God is for us, who can be against us?" 

Even if you have to suffer to remain pure in your love of God, the end of it will be more gloriously blessed than you can imagine. Don't fear those people who are against God's ways. Stand up to them in love, sharing  with them the love and hope that God has granted to you. This will give great glory and honor to Christ. 
It will be a lot better to stand fast in God's will, by His strength, than to suffer punishment for evil actions. 

 

1Pe 3:13-17  "Now who is there to harm you if you are zealous for what is good?  But even if you should suffer for righteousness' sake, you will be blessed. Have no fear of them, nor be troubled, but in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect,  having a good conscience, so that, when you are slandered, those who revile your good behavior in Christ may be put to shame." For it is better to suffer for doing good, if that should be God's will, than for doing evil."

Remember what Jesus Christ did, how He suffered because of your sinfulness. You were unrighteous, evil and He was pure and without sin. He suffered so that you could die to the desires of the flesh and be made alive to the Holy Spirit. The Spirit of love, He is Absolute Love. 
It was like you were imprisoned by your unbelief, but you were awakened to obedience.
When God judged the evil unbelief by a great flood Noah and His family believed and through obedience were saved. 

1Pe 3:18-20  "For Christ also suffered once for sins, the righteous for the unrighteous, that he might bring us to God, being put to death in the flesh but made alive in the spirit, in which he went and proclaimed to the spirits in prison, because they formerly did not obey, when God's patience waited in the days of Noah, while the ark was being prepared, in which a few, that is, eight persons, were brought safely through water." 


Now it is you act of belief in Baptism that saves you in the same way. The obedience you show, in demonstrating your death to self and being raised to new life in Jesus Christ, is like an inward washing of your guilt before God. 
In this you demonstrate the Lordship of the risen Christ, acknowledging that He is ruling at God's right hand. His kingdom rule has begun in you and all things are under His command. 


1Pe 3:21, 22  "Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a good conscience, through the resurrection of Jesus Christ, who has gone into heaven and is at the right hand of God, with angels, authorities, and powers having been subjected to him."
