It is very dangerous to go into eternity with possibilities which one has oneself prevented from becoming realities. A possibility is a hint from God. One must follow it. In every man there is latent the highest possibility, one must follow it. If God does not wish it then let him prevent it, but one must not hinder oneself. Trusting to God I have dared, but I was not successful; in that is to be found peace, calm and confidence in God. I have not dared: that is a woeful thought, a torment in eternity.
