Jesus Christ destroyed the power of death with His resurrection power providing eternal life for those who repent and turn their life over to Him.
1 Cor 15:26 The last enemy that will be destroyed is death.
God’s plan for us is eternal life, and Jesus purchased our eternal life on the cross, so we don’t have to fight the battle of life on your own- He won that fight for us.
1 Cor 15:55 – 58 The power of death was destroyed so that we can be steadfast, immovable, always abounding in the work of the Lord.
Jesus isn't telling us to carry the sin of all mankind but to learn how to cast our burdens upon Him who carried all of humanity's sin and burdens to the cross. - B Spada
