Does God strengthen us in our weakness?

Les teaches that God can strengthen us in our places of infirmity. He explains that we often do not know what we should pray for as we ought, but the Holy Spirit Himself makes intercession for us with groanings that cannot be uttered. Les notes there come places in life where we simply don't know how to pray; we may have an idea of what we want but cannot put it into words. His counsel is to be quiet and let the Holy Spirit commune for you. He clarifies this is not necessarily a tongues experience; Paul is not talking about that. Instead, the Holy Spirit actually intercedes on our behalf. Les also distinguishes this from the different intercessory power John mentions in 1 John 2, where John addresses believers and urges them not to sin, stressing that grace is not license.
