You may say that you have neither the power nor the means to lead souls to God; though you would willingly do so, you do not know how, as you can neither teach nor preach as did the Apostles. As the difficulty probably often crosses your minds on account of the desires our Lord gives you of serving Him. The devil frequently fills our thoughts with great schemes, so that instead of putting our hands to what work we can do to serve our Lord, we may rest satisfied with wishing to perform impossibilities.
You can do a great work and one most pleasing to our Lord: by doing all that is in your power, you would prove to His Majesty your willingness to do still more and He would reward you as if you had won Him many souls. I will conclude with this advice; do not build towers without a foundation, for our Lord does not care so much for the importance of our works as for the love with which they are done. When we do all we can, His Majesty will enable us to do more every day. If we do not grow weary, but during the brief time this life lasts (and perhaps it will be shorter than any of you think) we give our Lord every sacrifice we can, both interior and exterior, His Majesty will unite them with that He offered to His Father for us on the Cross so that they may be worth the value given them by our love, however mean the works themselves may be. May it please His Majesty, that we may all meet together where we may praise Him forever, and may He give us His grace.
