We may feel the peace of the Lord most of the time, but the test comes when someone misunderstands you or says something you feel uncalled for about you. Then you lose your cool. To remain objective and admit that we can be wrong is most difficult for mankind to deal with.
We know that God is always present with us, but we need to practice this awareness. If I am aware that he is watching me at all times, I know I would behave a lot better before others. Since Jesus and the Father are in each other, I believe that the even better practice is be aware that God actually dwells in us. Catholics are blessed to have the Lord truly present in the Holy Eucharist and receiving this Blessed Sacrament regularly greatly facilitates or strengthens our union with him. Now we have the Lord sitting on a throne in our hearts. Yes, we have been dethroned – the best thing that could possibly happen to us. Now, not only God is with us, we are in each other as one, doing all things together in perfect harmony.
