If there is one thing a Christian should do before he dies is to learn to pray.
The diciples went and asked Jesus to teach them to pray, not to teach or preach or heal or prophecy or evangelize but to PRAY. There must have been something in the way Christ prayed that made the disciples want to have the kind of relationship Christ had with the Father. Christ was a man devoted to prayer first and then to ministry He knew that He could do nothing apart from the Father, how come so many Christians today think they can do Christ's work without following His example of prayer?
