1:22 - Having purified your souls by obedience to the truth, in uncorrupted brotherly love earnestly love one another from the heart 1:23 - you have been born again not from perishable seed, but from imperishable seed, through the living and abiding word of God
Main point summary
Love one another. We are going to live together forever.
1 Peter 1:22-23
Τὰς ψυχὰς ὑμῶν ἡγνικότες
Having purified your souls
ἐν τῇ ὑπακοῇ τῆς ἀληθείας
by obedience to the truth
εἰς φιλαδελφίαν ἀνυπόκριτον,
in uncorrupted brotherly love,
ἐκ καθαρᾶς καρδίας ἀλλήλους ἀγαπήσατε ἐκτενῶς
earnestly love one another from the heart
you have been born again
οὐκ ἐκ σπορᾶς φθαρτῆς
not from perishable seed,
but from imperishable seed ,
διὰ λόγου ζῶντος θεοῦ καὶ μένοντος.
through the living and abiding word of God
Vs. 22: While this could be interpreted as an action-result relationship (you have purified your souls... love one another), inference emphasizes the logical imperative of verse 22 (love one another... your souls have been purified!) Vs. 23: Peter qualifies the kind of salvation that we have (an eternal kind). He also explains how it was accomplished (through God's word) which he explains in the next few verses when he quotes Isaiah 40:6 and 8 (All flesh is like grass and all its glory is like the flower of grass. The grass withers, and the flower falls, but the word of the Lord remains forever.") This is reinforcing his point that what God has set decreed with endure. Relationship between 22 and 23: We must purify our souls and love one another because we have been born again into a specific type of life, an eternal one.
So what does this mean? 1. Obedience is key - it is the means by which we are sanctified and how we experience Christian community. 2. The people that Peter is referring to when he says, "love one another" are other believers: our fellow church members, our roommates, husbands and wives, parents and siblings, professors and peers... the list goes on. Not only is our new life eternal, but so are the relationships that come with it (brothers and sisters in Christ). I think it's profound how in order to stress the imperative to love, he reminds us of all of eternity ahead which was established by the word of God. We'll be together forever, we might as well figure out how live peacefully. 3. So pursue reconciliation with one another, properly order your possessions and responsibilities with discernment and attentiveness to the Spirit, actively engage in your Christian community (especially your church), find unique ways you can apply the gifts God has given you, seek to bring unbelievers into this eternal relationship, and see all of this as the practical application of the reality of Christ's work in you.
