We must in all things seek God. But we do not seek Him the way we seek a lost object, a "thing." He is present to us in our heart, in our personal subjectivity, and to seek Him is to recognize this fact. Yet we cannot be aware of it as a reality unless He reveals His presence to us. He does not reveal Himself simply in our own heart. He reveals Himself to us in the Church, in the community of believers, in the koinonia of those who trust Him and love Him.
Seeking God is not just an operation of the intellect, or even a contemplative illumination of the mind. We seek God by striving to surrender ourselves to Him whom we do not see, but Who is in all things and through all things and above all things.
Thomas Merton. Seasons of Celebration. (New York: Farrar, Straus & Giroux, 1950): 223-224.
To live for oneself alone is to die. We grow and flourish in our own lives in so far as we live for others and through others. What we ourselves lack, God has given them. They must complete us where we are deficient. Hence we must always remain open to one another so that we can always share with each other.
