How do we know Christ gave Himself for the church?

The truth that Christ gave Himself for the church is powerfully presented in Ephesians 5:25, where Paul instructs husbands to love their wives as Christ loved the church. This love was demonstrated through His sacrificial death, indicating that He fully committed Himself to the redemption and sanctification of His people. By giving His body and shedding His blood, He not only purchased the church but also united Himself with it, making each believer a vital part of His body. Therefore, the act of giving Himself is central to understanding the nature of the church and His relationship with it.
