What does the Bible say about Christ's sufficiency?

Scripture portrays Christ as our complete sufficiency, emphasizing that apart from Him, we have no merit. In 2 Corinthians 3:5, Paul writes that we are not sufficient in ourselves, but our sufficiency comes from God. This means that Christ fulfills all our needs and takes on our unworthiness, providing salvation and intercession. His sufficiency extends to every area, including justification, sanctification, and assurance, ensuring that believers can confidently approach God knowing they lack nothing in Christ.
