Prayer is so vitally important to the Christian walk.  We get strength from it, encouragement, wisdom, and power from it.  It draws us close to God and allows us to have an intimate relationship with him.  Knowing the importance of prayer though does not automatically give us all the benefits of prayer.  We need to use it and rely on it more often.  We need to stop trying to do things on our own and in our own power.  It is only when we are faithful in prayer that we can tap into the wonder-working power of God and we will see the difference in our lives.  When we pray, things change. Period.
