Jesus died to fulfill the scriptures and spread the Word of God. No where in the gospels does He say He died to forgive sins. If you ask God your sins are forgiven.

8 But God shows his love for us in that while we were yet sinners Christ died for us. 9 Since, therefore, we are now justified by his blood, much more shall we be saved by him from the wrath of God. 10 For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life. 11 Not only so, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received our reconciliation. - Romans 5:8-11
22 Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins. - Hebrews 9:22

21 And you, who once were estranged and hostile in mind, doing evil deeds, 22

18 You know that you were ransomed from the futile ways inherited from your fathers, not with perishable things such as silver or gold, 19 but with the precious blood of Christ, like that of a lamb without blemish or spot. - ! Peter 1:18-19
