In Why Stay Catholic?, Michael Leach quotes Karl Rahner, S.J. and it is a remarkable passage:
Thanks to your mercy, O Infinite God, I know something about you not only through concepts and words, but through experience. I have actually know you through living contact.
I have met you in joy and and suffering For you are the first and last experience of my my life. Yes, really you yourself, not just a concept of you, not just the name which we ourselves have given to you!
You have descended upon me in water and the Spirit, in my baptism. And then there was no question of my convincing or excogitating anything about you. Then my reason with its extravagant cleverness was still silent. Then, without asking me, you made yourself my poor heart’s destiny.
God is our hearts’ destiny… how wonderful is that?
