There have been times in my life that I have been so desperate, the only words I could pray were "Help me!" But you know, that is all that is necessary. Matthew 6:8 says, "And when you pray, do not keep on babbling like pagans, for they think they will be heard because of their many words. Do not be like them, for your Father knows what you need before you ask him."
So what might be a starting point to assist people to learn to pray? Teach them to say to the Lord, "Help me!" Teach them to pray for others saying, "Help Jeff" or "Help Mary!"
God not only know what your heart is in praying those prayers, but He also knows what the individual being prayed for needs. This is a good starting point in understanding prayer.
