By Baptism all sins are forgiven, Original Sin and all personal sins, and temporal punishment due to sin is removed. After one has been reborn in Christ, there is nothing to prevent one’s entry into God’s Kingdom.
However, though all sins are removed, there remains, as an effect of Original Sin, the inclination to sin that is called concupiscence . This inclination to sin shows itself in what is sometimes referred to as a dark- ening of the mind and a weakening of the will, that is, the inability to know clearly the right or wrong of an action and/or the lack of strength to resist temptation and always to do the right thing no matter how hard this is. The effects of Original Sin need not harm us so long as we seek strength to resist them through the Sacrament of Penance, the Sacrament of the Eucharist, prayer, a deepening spirituality, growth in virtue, and a wholehearted dependence on God.
