Resurrection would not be possible if redemption didn't happen. Death must occur. Redemption is upon the death of Jesus. The death of Jesus on the cross isn't worthless! Jesus couldn't have entered into heaven if the wages of sin haven't been fully paid. This is upon His death. The way to the most Holy Place is the blood which is significant that death has happened. A sacrifice has been ordained has been made. Without this no entry. Jesus accomplished this and He entered for us and as us. Glory to God..
