What does the Bible say about God's pleasure in Christ?

In Isaiah 53:10, it is recorded that 'it pleased the Lord to bruise Him; He has put Him to grief.' This passage underscores the sovereign pleasure of God in the sacrificial atonement of His Son, Jesus Christ. The idea here is fundamental to understanding the Reformed perspective on salvation, as it emphasizes God's initiative in redemption and the essential role of Christ in fulfilling God's divine purposes. The suffering and sacrifice of Christ were not arbitrary but were integral to God's plan for the salvation of His elect, demonstrating His justice and mercy simultaneously.
