When we pray, we should always ask the Holy Spirit to pray through us. He is God on this earth. We truly don't know the root cause of a person's problem, but the Holy Spirit does. He uses our mouth to make intercession through us (Romans 8:26-27). One day as I was praying for a person, these words came out of my mouth, "Set your affection on things above, not on things on earth." I knew these words were in Scripture; but at that particular time, I was not thinking about that verse. I then IMMEDIATELY knew the Lord by his Spirit was praying through me for this individual and the Holy Spirit was making known the person's root cause for their problems. I then decided to dissect that verse. I began by looking at its meaning in the dictionary and found that the word "set" means "to initiate action or process"; and "affection" means "love, fondness, warmth, friendliness and tenderness"; and "things" means "affairs, which is general matter or circumstances". Listen to the Holy Spirit talk to you! Shalom.
