Since therefore, we have now been justified by His blood, much more shall we be saved by Him from the wrath of God. — Romans 5:9
Jesus died for us, to ensure that our sins would be forgiven. His blood was shed so that we would be reconciled with God and not face His anger due to our sinful lives.
If we sincerely believe that Christ did die for our sins when he shed His blood on the cross, then God will accept this faith in Jesus and not judge us on our lives, but will accept our debt as paid through this faith.
Jesus did not die for Himself, but for us. All that Jesus asked from us was to believe and have faith, in Him and His victory over death.
Thank You, Lord, for asking so little of us, but giving everything Yourself. Amen.
