Good Friday is absolutely the correct title. Yes, the horrific treatment Jesus was going through was terrible and led to a barbaric death. However, at the same time and, in fact the reason for His death was He was becoming sin. He became or took upon Himself our sin. So now when Our Heavenly Father considers and sees us, He sees us as innocent because of what Jesus accomplished. So it is good, very good for us, the sacrifice Jesus made for us today. Only good and not great? The Greater thing comes three days hence with His resurrection. Let us live into that sacrifice and see the greatness of His Good act.
