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.
