In Praise of the Holy Trinity

In a retreat reflection that she wrote for her sister Marguerite, a mom with small children, Saint Elizabeth of the Trinity sets the life of heaven as the ideal to seek. Yet, she does not propose heaven as simply a remote future possibility. Through a complete surrender of our whole existence to God, the life of heaven is a way of life that begins now. This means that the glory that awaits us is the same glory already present to us now. We are meant to be the praise of this glory - creatures who make known the inexhaustible riches of God:

In Heaven, each soul is a praise of glory to the Father, the Son and the Holy Spirit. This is because each soul is fixed in pure love. Each one "no longer lives its own life but the life of God" (St. John of the Cross).  The soul "knows itself", says Saint Paul, "as it is known by God." Its will the will of God. Its love the very love of God.  

In reality, the Spirit of love and power transforms the soul.  Given in order to supply what is lacking, as Saint Paul explains, the Holy Spirit accomplishes this glorious transformation in it (see Romans 8:26).  Saint John of the Cross affirms that for the soul that has surrendered to God, little is left to; by the power of the Holy Spirit, it attains the degree of which we are speaking here below! This is what I call a perfect praise of glory!

Heaven in Faith, 42.
