It always fascinates me that Jesus prayed when he walked on the earth ! I mean, he of all people had every excuse not to pray and yet He did. Probably, His disciples saw how effective His prayers were which prompted their question in Luke 11 :
"...Lord teach us to pray..." they said. That resulted in Jesus giving them what is recited in most Christians circles as the "Lord's Prayer". I think praying the Lord's Prayer as we do is powerful. But even more powerful is the fact that I sincerely believe that Jesus gave us the Lord's prayer as a guide also ! A guide to effective prayer and spending time with the Father.
