Sanctifying and actual grace
Sanctifying grace remains permanently in the soul as long as one does not reject one's adopted sonship by committing a mortal sin, which severs one's friendship with God. Less serious sins, venial sin, although they "allow charity to subsist, they offend and wound it." However, God is infinitely merciful, and sanctifying grace can always be restored to the penitent heart, normatively in the Sacrament of Reconciliation (or Sacrament of Penance).
