I do not want you to be unaware, brothers, how often I planned to come to you (but have been prevented from visiting until now), in order that I might have a harvest among you, just as I have had among the other Gentiles.
— Romans 1:13
That is why I have often been hindered from coming to you.
— Romans 15:22
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.
