Life is all about how much you submit yourself to God. Our time on earth is limited. We can let God be our God or play God ourselves—these are the two extremes. As long as we do our best to let God be our Lord, we are on the right track. Once you attain union with God through the Holy Eucharist, you belong to him totally and are ready to enjoy eternal life. Receiving the flesh and blood of the Lord completes and perfects that union.
