"LIVE GENEROUSLY AND WITH A REASONABLE HEART."
God has many ways of calling His servants into His service. Sometimes He makes use of sermons, at other times of the reading of good books. There are those who have been called by hearing the holy words of the Gospels like St. Francis and St. Anthony. Others have been called by weariness, disasters, and sorrows which came upon them in the world.
Our Lord has often made use of such means to call many to His service, who otherwise would certainly never have entered it. For although God is Almighty and can do whatever He wills, yet He does not will to deprive us of the liberty which He has once given us; and when He calls us to His service, He wants us to come of our own free will, and not through force or constraint.
(St. Francis de Sales, Spiritual Conferences, Conference XVII)
"If any of you hear the Lord's inner call to give yourselves completely to him in order to love him 'with an undivided heart' (cf. 1 Cor 7:34), do not be held back by doubts or fears. Say 'yes' with courage and without reserve, trusting him who is faithful to his promises. Did he not assure those who had left everything for his sake that they would have a 'hundredfold in this life and eternal life hereafter'? (Cf. Mk 10:29-30)." Pope John Paul II
