God brings you to places, among people, and into certain conditions to accomplish a definite purpose through the intercession of the Spirit in you. Your part in intercessory prayer is not to agonize over how to intercede, but to use the everyday circumstances and people God puts around you by His providence to bring them before His throne, and to allow the Spirit in you the opportunity to intercede for them. In this way God is going to touch the whole world with His saints.
