The principal expression of our worship to God is that of the Mass. From the Introductory Rites, to the Liturgy of the Word, to the Liturgy of the Eucharist and ending with the Concluding Rite are all part of our praise and thanksgiving offering.
Mass was instituted by Christ himself at the Last Supper and by participating we confer the graces needed from God’s mercy to expiate the sins of the past and the graces needed from God’s bounty to obtain His blessings for the future.
Yet a time is coming and has now come when the true worshipers will worship the Father in spirit and truth, for they are the kind of worshipers the Father seeks.
The one who sows sparingly will also reap sparingly, and the one who sows bountifully will also reap bountifully. Each of you must give as you have made up your mind, not reluctantly or under compulsion, for God loves a cheerful giver. And God is able to provide you with every blessing in abundance, so that you may share in every good work.
