Scripture Commentary 1 Peter 3

Was it more than a physical bearing of sin that Christ offered up for His chosen ones, was His Soul an offering? How are His chosen sinners dead to sin? Was this healing that Christ worked out the only way? Why did the LORD make the woman the weaker vessel? What does Peter mean 'to eschew evil'? Who are these righteous ones? Why is immersion taught in Scripture as the mode for baptism?
