Fighting your battles through prayer takes more than knowledge and conceptually understanding. Spiritual warfare takes faith and application. You really do need to rely on God and communicate openly with Him. You plead, pour out, repent, thank, request, and honor God in your prayers. When you do this you deny the enemy power over you. You resist Satan by turning to God who gives you victory.
Victorious prayer comes from knowing what the problem is and turning it over to God in prayer. You trust the Holy Spirit to use what you say and fill in the blanks to advocate for you. He is the one that empowers your prayers. You have the Holy Spirit living within you if you are a true Christian. He knows and understands what you need better than you because He is not distracted by outside sources.
Victorious prayer can happen when you ask God to remove distraction and you take a real hard look at your life. You see what the problem is and you decide to do something about it in prayer. You trust God to handle the details, so you can let go of certain aspects. Pray over your own heart condition. Pray to close the door that Satan has access to your heart or mind. Seal them closed with kindness, mercy, forgiveness, and love like Jesus. Never stop praying for God's will.
You pray over the people in your life, your issues, and the ability to be consciously aware. The Holy Spirit will lay certain things on your heart to pray over, but you also need to be aware of what is happening in life around you. The battlefield is real, but you can be victorious in God's name.
