The Holy Spirit Speaks For Us When We Cannot

As Christians we understand that God knows all things so He already is aware of what we will converse with Him in Prayer even when we cannot put it into words. This Scripture I read this morning strengthens me even more.
    In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans. And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for God’s people in accordance with the will of God. (Romans 8:26-27)
Does this mean we do not have to speak on things that we should know we need God’s help and just let the Spirit take it for us even though we do not think it needs to be said in prayer? No. When we are weakened, God caries us through. The Spirit speaks on matters that are unknown to us. After all, if we are of clarity of mind and have knowledge of the occurrences around us we should be of a heart of understanding our own needs. These we take to God in prayer. It is when our mind is so deeply fogged with worldly things that the Spirit intercedes because we do not see what is happening.
Here are a couple of examples: In today’s world of a drug for every ill sometimes our minds get so clouded we have no idea what is happening and the result is sometimes detrimental to ourselves and our relationships with those close to us. I can honestly say this has happened to me. It took an incident for me to realize that I had been altered by the drugs (do not worry I am good now).                                                                                                                                 
 Also, our minds can get so wrapped up in our sins that there is no escape, we lose hope and our worthiness, blinded by the sins and false idols. If we recognize this and cannot speak because we are afraid of the consequences, here is another time where the Holy Spirit sees our pain, knows our heart, intercedes and we are opened up to a right course of action.
Jesus said that He was sending a helper that would be with those who believe and accept Him. This helper is the Holy Spirit that was awakened within us. Jesus ignited the Spirit inside the Apostles (Pentecost) as the visual representation of what we are to feel inside when we accept Him. It is that burning that ignites in us when we are baptized, when we are lead to witness, when we worship, when we are called deeper into His service.
The Spirit tends that gut feeling when we feel sick after doing something we know we should not have done that if heeded, awakens us to make ourselves right with God. 
 The Spirit helps us in our weakness and there are some things that yes, our words cannot express.
