How could we know the difference between the presence of the Lord, and the presence of the Evil One?

We must daily ask God for discernment, to distinguish right from wrong and good presence versus evil presence. Many times we allow the desires of our hearts to deceive us. God is not a deceiver, he will not lead you into any path that has regrets. Knowing how to hear the voice of God comes from spending time in his presence, meditating on his word and listening attentively to him when he speaks to us. The more time you spend with God the more you will come to know him and understand his will for your life, so that you are no easily deceived by the Evil One. The presence of the Lord is peaceful, the presence of the Lord is joyful, and the presence of the Lord is spirit-filled. Come to know God in an intimate way, for unless you are at peace with him, you will not be able to hear his voice.
