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.
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?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
It is possible through prayer, receiving the sacraments, self denial/mortification (e.g. fasting etc.), christian discipline and pious living to become completely detached from all sin and in a state of holiness and grace. Such go straight to heaven at the time of their death and receive a very high reward in heaven. But there will always be a lingering tendency to sin even if one is in a high state of grace and let’s their guard down. This is why in the Lord’s prayer we say “and lead us not into temptation but deliver us from evil”. Jesus saves not only though forgiveness of sins but also by leading us away from sin so we have less opportunity to stumble. In fact this is how Mary was saved from all sin and remained sinless all Her life. God made a special exception for her to be born sinless without original sin so that she would truly be “blessed above all women” (including Eve who was born without original sin). But it was Jesus, the human-divine manifest 2nd person of God who saved her from committing personal sin during her earthly life by leading her away from the occasion of sin. No doubt Mary was subject to occasional temptation as was Jesus but she was protected from a large part of it by her committed pious life and closeness to Jesus.Can concupiscence, the inclination to sin, be conquered during our lifetime though growing in holiness?
