Who can overcome sin?

“I can do everything in Christ Jesus who strengthens me” (Phil.4:13). We can overcome all sins in our life by the grace of God. What does the term ‘Sin’ mean? “Sin is “a word, an act, or a desire contrary to the eternal Law” (Saint Augustine). It is an offense against God in disobedience to his love. It wounds human nature and injures human solidarity. Christ in his passion fully revealed the seriousness of sin and overcame it with his mercy.” According to St. Augustine, “Sin is the will to keep or to get what one can freely leave alone that justice forbids.” “Sin is not a desire for naturally evil things but an abandonment of better things. And this itself is evil, not that nature which the sinner uses evilly.” ( Griffiths J. P, Lying: an Augustinian Theology of Duplicity, Brazos Press, Oregan, 2004, P.57.) The word of God defines sin very clearly and also magisterial teaching describes, explains, defines with clarity. “… sin is an abuse of the freedom that God gives to created persons so that they are capable of loving him and loving one another” (CCC 387).
