Calling on the LORD

What is 'slot machine faith' and why do people continually pursue it? Why did the LORD answer Elijah? Does anyone know how to pray or are those who say they do liars? How is prayer spontaneous, with words that cannot be uttered and can only be given by the Holy Spirit of Christ? How is the Spirit given act of 'calling on the LORD' an act of worship? What is it that needy sinners need to hear continually? How is true worship always from a position of lowliness looking up in hope to Christ lifted up on high? Does true worship always focus on the Lamb Slain alone?
