The best way they can prepare themselves for Africa is to grow in holiness. "The holier you are, the greater will be our capacity for serving God and saving souls." They open themselves to God's grace through practice of the virtues, particularly, "humility, mildness, charity, the spirit of prayer, and crowing all, obedience."
They will strengthen the spirit of their vocation by loving the Lord with all their heart and with generosity. "Sacrifice for Him all that is agreeable to you. When troubled by pain or temptation, bear them with love, peace and patience."
