"Finally, be ye all of one mind, having compassion one of another, love as brethren, be pitiful, be courteous:" - 1 Peter 3:8 KJV
At face value it sounds in English like the writer is telling us to be something or do something. Here is a newer translation...
"Finally, all of you, have unity of mind, sympathy, brotherly love, a tender heart, and a humble mind." - 1 Peter 3:8 ESV
But in truth it is hard verse to translate if you look at the Greek is says something like... 'In the end or lastly... unity, compassion, brotherly love, a capacity to be in a good mood because of a good stomach, kindness in a simple way... for all'
These aren't things we do. They are results of living in what has been done.
"Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, who by God's power are being guarded through faith for a salvation ready to be revealed in the last time. In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials, so that the tested genuineness of your faith - more precious than gold that perishes though it is tested by fire - may be found to result in praise and glory and honor at the revelation of Jesus Christ. Though you have not seen him, you love him. Though you do not now see him, you believe in him and rejoice with joy that is inexpressible and filled with glory, obtaining the outcome of your faith, the salvation of your souls." - 1 Peter 1:3-9 ESV
We have an inheritance and we are sealed with the Spirit of God.
"And it is God who establishes us with you in Christ, and has anointed us, and who has also put his seal on us and given us his Spirit in our hearts as a guarantee." - 2 Corinthians 1:21-22 ESV
We are heirs with a credit line based on that future inheritance. We can draw on peace. We can live like rich people. Jesus is the real thing.
