ACC ~ Mark 3 v5c

COOPERATING WITH GRACE. CHRYSOSTOM: I exhort you that you not carelessly slumber so as to leave everything to God. Nor, when diligent in your endeavors, imagine that by your own exertions the whole work is achieved. God does not will that we should be indolent. For God does not do the whole work by himself by fiat. Nor is it his will that we should be entirely self-sufficient. For God does not commit the whole work to us alone. [1] THE GOSPEL OF ST. MATTHEW, HOMILY 82. [2]

[1] Cf. Ps 146:5; Is 41:10; 50:7; Acts 26:22.

[2] TLG 2062.152, 58.742.57-743.5; GMI 59*. Neither should we leave everything to God as if God required nothing of ourselves, nor should we leave everything to ourselves as if God did not supply grace for the will.
