What does the Bible say about Christ being all in our salvation?

In 1 Corinthians 1:30, the Apostle Paul declares that it is of God that we are in Christ Jesus, who has been made unto us wisdom, righteousness, sanctification, and redemption. This emphasizes that every aspect of our salvation hinges upon Christ alone. He fulfilled the law perfectly and provides the righteousness required by God. Our sanctification and redemption, which involve not just the forgiveness of our sins but also our new identity, are fully realized in Christ. Thus, Christ's total sufficiency is foundational for understanding the entirety of salvation.
