What is the difference between sanctifying and actual grace?

Sanctifying grace is a stable gift that makes us holy and able to live as God's children. Actual grace is God's help moving us toward conversion, goodness, and deeper holiness in particular moments.

Grace comes first. Every grace is God's free and undeserved gift (CCC 1996). We cannot earn the beginning of salvation or make ourselves share in divine life. God acts first, awakening faith, moving the heart to repentance, and enabling our response. Even our cooperation is supported by grace, though it remains a truly free human response (CCC 2001-2002). As Jesus says, "Apart from me you can do nothing" (Jn 15:5).

Sanctifying grace remains in the soul. Also called habitual grace, sanctifying grace is a stable supernatural disposition that perfects the soul and enables us to live with God and act by His love (CCC 1999-2000). It is first given in Baptism, which makes us a new creation and an adopted child of God (CCC 1265-1266). Through this grace we share in the divine nature, without becoming God by nature (2 Pet 1:4). Sanctifying grace grows through prayer, the sacraments, charity, and faithful obedience.

Actual grace helps us act. Actual graces are particular interventions by God, whether at the beginning of conversion or throughout the work of sanctification (CCC 2000). An actual grace might move someone to confess a long-hidden sin, resist temptation, forgive an enemy, begin praying, or perform an act of charity. Actual grace can be offered even to someone who lacks sanctifying grace, drawing that person back to friendship with God. We can cooperate with such grace or resist it (Acts 7:51).

Sin affects grace differently. Venial sin wounds charity but does not deprive the soul of sanctifying grace (CCC 1863). Mortal sin destroys charity in the heart and causes the loss of sanctifying grace (CCC 1855, 1861). God still offers actual graces calling the sinner to repentance. Sanctifying grace is ordinarily restored through sacramental confession, where Christ reconciles the sinner to Himself and His Church (CCC 1446, 1468).

In daily life. Stay in sanctifying grace by avoiding mortal sin and receiving the sacraments faithfully. When you sense a prompting to pray, repent, serve, or resist sin, respond promptly. That may be an actual grace inviting your cooperation.
