We’re actually forgiven of injustice and then also made just, at baptism. We are heaven-bound if dying at that point, provided sincere faith was present. But if we live on, we’re to then remain in that state of justice, and expected to grow in it. Actual justice/righteousness: faith, hope, and love, are gifts that are given to us, but in nascent seedling form at that point, a form which is then to be cultivated, nurtured, and grown- and increasingly “owned” by ourselves as we work together with He who works in us-and with He who will ultimately judge the outcome, of how well we did with what we were given.
1274 The Holy Spirit has marked us with the seal of the Lord (“Dominicus character”) "for the day of redemption."86 "Baptism indeed is the seal of eternal life."87 The faithful Christian who has “kept the seal” until the end, remaining faithful to the demands of his Baptism, will be able to depart this life "marked with the sign of faith,"88 with his baptismal faith, in expectation of the blessed vision of God - the consummation of faith - and in the hope of resurrection.
1263 By Baptism all sins are forgiven, original sin and all personal sins, as well as all punishment for sin.66 In those who have been reborn nothing remains that would impede their entry into the Kingdom of God, neither Adam’s sin, nor personal sin, nor the consequences of sin, the gravest of which is separation from God.
1264 Yet certain temporal consequences of sin remain in the baptized, such as suffering, illness, death, and such frailties inherent in life as weaknesses of character, and so on, as well as an inclination to sin that Tradition calls concupiscence , or metaphorically, “the tinder for sin” (fomes peccati) ; since concupiscence "is left for us to wrestle with, it cannot harm those who do not consent but manfully resist it by the grace of Jesus Christ."67 Indeed, "an athlete is not crowned unless he competes according to the rules."68
"A new creature"
1265 Baptism not only purifies from all sins, but also makes the neophyte “a new creature,” an adopted son of God, who has become a "partaker of the divine nature,"69 member of Christ and co-heir with him,70 and a temple of the Holy Spirit.71
