What does the Bible say about Christ's suffering for us?

According to 1 Peter 4:1, Christ suffered in the flesh for us, highlighting the necessity of His incarnation. God, in His perfect justice and mercy, could not redeem humanity without becoming man to bear the wrath due for our sins. This act of suffering not only satisfies God's justice but also demonstrates His immense love for His people, whom He chose before the foundation of the world. The Gospel underscores that Christ laid down His life specifically for those given to Him by the Father, affirming His role as our substitute in a way that provides redemption exclusively for His elect.
