Christian, if we want to have our hearts filled with divine love, we must first empty them of the love of this world, it frivolous and sinful customs, and then turn our hearts to the one God, our only good and happiness and eternal beatitude.
Then, we will live lives of constant joy and gratitude toward our Lord. Then, we will experience (at least partially) the happiness of paradise after the end of time, after the second coming.
