The quote emphasizes the value of having a heart focused solely on God's intentions, free from personal agendas. This kind of heart finds peace and contentment in its emptiness, allowing it to be filled with divine love. Without the distractions of self-interest, one can experience a deep connection to God and others.
Furthermore, the solitude that comes from this selfless heart can transform into a powerful form of prayer. Rather than feeling lonely or isolated, individuals can use their quiet moments to grow closer to God, finding strength and guidance through their faith, as illustrated by Elisabeth Elliot in her book.
