When we just do not know what to pray, here is a really simple one that Jesus taught us.  So short and simple.  This prayer takes care of our needs and God’s needs.  It actually starts with God’s needs, which is the Kingdom.

Our Father who is in heaven, may Your name be sanctified.  May Your Kingdom come.  May Your will be done on earth as it is in heaven.  And supply us today what we need and forgive us our wrongs as we forgive the wrongs of others.  Do not lead us into temptation, but deliver us from evil.
