Fear vs love.
The only way one is able to feel fear is when the person is operating from their brain/mind/ego. Ego is an artificial entity, the false sense of self, created by the feedback that we receive from the external world (But remember that from "east, west, south and north", i.e external world, come the influence of the devil.
God, in the other hand, is available when one looks deeper within. Being closer than "jugular vein", one gets the feeling of closeness with God. Love is the feeling that God has put within us, it is the feeling that connects us to our creator.
In order to feel love, one needs to open up the heart (with the closed heart one is purely in the mind, operating from the ego, thus making Ego the leader) and simply surrender. Love can not be forced, it can only surrendered into.
When one is experiencing love, there is no place for fear. When one is experiencing fear, there is no space for love.

So this is how it works for me. When I am love, I am in a state of surrender. I have surrendered my mind, my ego, my will to that of love. In that state I experience compassion, appreciation, peacefulness. In that state, the best way for me to go makes itself known to me. My life is filled with synchronicities and things come easily. I feel blessed.
When I feel fearful, it is because of what is in my mind - the thoughts that I think are making me feel this way. It is an unbalanced, closed state. In a state of fear I feel limited, stuck, not very free. In order to free myself from it, I need to stop, relax, open up my heart, and allow love to take over. I need to let go of fear. I need to let go of the thoughts that bring on the fear. Fear is to do with the worries and uncertainties of the future. But by handing the future over to God, there is nothing to fear or worry about. There are only blessings to appreciate. and love.
The ego is fearful of God, because to be one with love is the death to the ego.
When I am one with love, there are no fears. There is only peace...
