John Henry Newman says

when man fell and lost this holy grace, he had various gifts still adhering to him; he might be, in a certain measure, true, merciful, loving, and just; but these virtues did not unite him to God. What he needed was holiness; and therefore the first act of God's goodness to us in the Gospel is to take us out of our unholy state by means of the sacrament of Baptism, and by the grace then given us to re-open the communications, so long closed, between the soul and heaven.
