"We remember Thomas Aquinas most as a high-powered theologian, whose stature we could never equal. But Aquinas is a saint, not because of his accomplishments, but because he lived a committed Christian life of humble prayer and service. That we can imitate, no matter what we do for work." - Bert Ghezzi, Voices of the Saints
I am not in league with St. Thomas Aquinas and probably never will be, but Bert Ghezzi's words, "But Aquinas is a saint, not because of his accomplishments, but because he lived a committed Christian life of humble prayer and service," gets to the heart of the matter.
Commitment is the key to everything we do in life isn't it? If we're not committed to our relationships or our work, things begin to unravel quickly. The same goes for our spiritual life only there's much more at stake.
I'll leave you with the great saint's own words:
God loves his creatures, and he loves each one the more, the more it shares his own goodness, which is the first and primary object of his love. Therefore he wants the desires of his rational creatures to be fulfilled because they share most perfectly of all creatures the goodness of god.
And his will is an accomplisher of things because he is the cause of things by his will. So it belongs to the divine goodness to fulfill the desires of rational creatures which are put to him in prayer.
