St. Teresa of Avila says we must work hard to acquire great virtues so God will come into our soul more fully. We receive the foundation of these virtues when baptized by God and the Spirit infuses them into each soul of the faithful. Each mortal is then capable of acting as His child who would merit eternal life. We must work hard in developing growth in bonding ourselves with God. A relationship with God is founded on love and fear of the Lord.
True love begins with supernatural prayer.
When the soul desires God, we will grow in the Spirit by a spark of his true, awesome love. It is the Spirit of God who enables the soul to love and worship God. When we possess God, we possess love. We possess God when we are in the state of grace. Love of God and love of neighbor.
