Naturally, the first thing is that you desire to know him; that is, you are open to him. Then he will start drawing you. This is the beginning. The process is gradual, but may accelerate at some points depending upon your disposition. You may not feel much that he is drawing you, then one day you look back and will see that the Lord is a lot closer to you than before. You reach the point at which you are aware of his holy presence at every moment, day and night. This is a great blessing, as it helps you stay holy.
