If you desire the worship that you give to God to be pleasing to Him and valuable for the salvation of your soul, put it properly into practice. Begin by preparing for holy Mass as soon as you are awake, uniting yourself to all the Masses which are being said at that moment. When the bell rings to call you to the house of God, consider the fact that it is Jesus Christ Himself calling you. Start out immediately, so that you will have a moment to meditate upon the tremendous act at which you are about to assist. Do not say, like those people who have no religion, that you have plenty of time, that you will be there soon enough. But say, rather, with the Holy Prophet: "I rejoice when I am told that we are going into the house of the Lord."
When you come out from your home, think about what you are going to do and what you are going to ask of God. Begin by clearing your mind of earthly matters so that you will be thinking of God only. Avoid all sorts of unnecessary conversations which serve no other purpose than to make you hear Mass badly. When you enter the church, recall to yourself what the holy patriarch Jacob said: How awesome is this place! How holy it is! It is truly the house of God and the gateway to heaven! When you get to your place, humble yourself profoundly as you think of your own unworthiness and the greatness of your God, Who, nevertheless, in spite of your sins, wishes to suffer you in His holy presence. Make an act of faith with all your heart. Ask God to give you the grace to lose none of the many favours which He grants to those who come here with good dispositions. Open your heart so that the word of God may enter it, take root in it, and bear fruit there for eternal life. Before leaving the church, do not fail to thank God for the graces He has just given you and go straight home, fully occupied with the thoughts of what you have seen and heard.
Yes, my dear children, if we conducted ourselves in this manner, we should never come away from the services of the Church without being filled with a fresh desire for heaven and a new disgust for ourselves and the things of this earth. Our hearts and our minds would be given over altogether to God and not at all to the world. Then the house of God would truly be for us the gateway to Heaven. That is what I desire for you.
