All in Interceding in Prayer

How do we pray in intercession? Do we give our own instruction to the person for whom we are meant to pray, or do we place their suffering and other needs before God by praying that His will be communicated, and done, for them? One of the greatest snares in intercession is to allow our own sympathy and will to step in between the person needing prayer, and God. When this happens we are not interceding for them, but counselling them instead. We are attempting to provide the aid ourselves that only God is qualified to give.
