Romans 8:26

In the same way the Spirit (comes to us and) helps us in our weaknesses. We do not know what prayer to offer or how to offer it as we should, be the Spirit Himself (knows our need and at the right time) intercedes on our behalf with sighs and groanings too deep for words. 

The Holy Spirit is our comforter and our intercessor sent to aid us in our prayers. Our thinking, past experiences, and five senses limit us. However, if we lean on Jesus and confess the word from the Bible and listen for guidance from the Holy Spirit, we will overcome.
