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
Can concupiscence, the inclination to sin, be conquered during our lifetime though growing in holiness? Meaning, if I become holy as Jesus and Mary were while I am here still on Earth, then would the inclinination to sin go away during this lifetime or only in the next?
