Why did Jesus Christ suffer and die? ( යෙසුස් ක්‍රිස්තුස් වහන්සේ දුක් විද කුරුසියෙ මරණය ලෑබුවේ ඈයි? )

Rom 8 2:4

For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death. 3For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: 4that the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit

රොම 8 1:4
