The Blessed Virgin received more than other mortals. Christians receive more than pagans. Those in the state of grace are likely to receive more than those in the state of mortal sin. In a way, our graces depend also on our dispositions. The principal ways of obtaining grace are prayer and the sacraments , especially the Holy Eucharist.
Actual grace is obtained by good works.
It is especially obtained by the use of means offered by the Church, such as offering Mass, listening to sermons, etc., and receiving the sacraments, particularly the Holy Eucharist, which contains God, the Source of Grace. Although we cannot merit grace by our good works, still our good works can beg God for us, to give us grace. Good works are necessary, for God will not save us without our cooperation. The first converts at Pentecost were moved by the preaching of the Apostles. We can resist the grace God, for our will is free, and God does not force us to accept His grace.
