Peter here calls for love of your brethren in Christ. Not just any love — love that is sincere (unhypocritical) and pure (singular, without any corrupting influence).
The reason Peter gives for this love is a response to our redemption through Jesus Christ. Being “born again.” Here though, he emphasizes the gospel of Jesus Christ, a gospel that he describes as “the word of God which lives and abides forever.”
This word is the incorruptible (imperishable) seed that brings about conversion. Paul agrees with this assessment saying in Romans 1:16, “For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek.”
Put in a nutshell: God has delivered for us the perfect vehicle to save us. The death, burial and resurrection His only begotten Son! As this is proclaimed, it brings faith to men, and salvation. As we receive this great gift, our response must be love for one another!
