What does the Bible say about Christ's love for the church?

The love of Christ for His church is demonstrated in Ephesians 5:25, where Paul writes, 'Husbands, love your wives, even as Christ loved the church and gave himself for it.' This love is particular, meaning it is directed specifically toward His chosen people, His bride. It is also eternal; according to Jeremiah 31:3, 'I have loved thee with an everlasting love,' indicating that His love began before the foundation of the world, as we see in Ephesians 1:4. Finally, it is a love that cannot be lost, reaffirmed in Romans 8:38-39, where nothing can separate us from the love of God which is in Christ Jesus our Lord.
