I watched about 3/4 of Fr. Mark Goring's testimony on how he came to know God on YouTube. Some of his experiences were similar to mine, so I am prompted to reiterate what I have said in the past again, for I think the message is important. Knowing God is simple to understand. God has done all the preparatory work and is waiting for your move. He has even knocked on your door before, but you did not hear him. What is essential is that you must leave your heart open – the wider the better. If you seek God and expect him to hear from him, but if your heart is closed, he's not going to barge in. Of course, there are exceptions. In the case of St. Paul, even when was persecuting Christians, Jesus called him directly to be his Apostle to the Gentiles. Roy Schoeman whose testimony I recently posted is another case. But for most of us, the fast and sure way to know God is to open your heart and invite God to enter. The wider you open yourself, the sooner you'll experience him. This is to show that you are humble and sincere in seeking him. If you keep God out, he's going to keep you out, or said perhaps more accurately, you'll keep yourself out by your own choice.
