We are coming to the end of our series on Prayer.  I hope many have been challenged, encouraged and spurred on to go deeper with God through prayer.  Tim Keller talks about 12 touchstones of prayer in his book "Prayer: Experiencing Awe and Intimacy with God."  Here is his helpful summary of them for your review and practice: 
Prayer 
What is is
- Work - Prayer is a duty and discipline
 
- Word - Prayer is conversing with God 
 
- Balance - Prayer is adoration, confession, thanks and supplication. 
 
What it requires
- Grace - Prayer is "in Jesus' name," based on the gospel. 
 
- Fear - Prayer is the heart engaged in loving awe. 
 
- Helplessness - Prayer is accepting one's weakness and dependence.  
 
What if gives 
- Perspective - Prayer reorients your view towards God. 
 
- Strength - Prayer is spiritual union with God. 
 
- Spiritual Reality - Prayer seeks a heart sense of the presence of God. 
 
Where it takes us 
- Self-knowledge - Prayer requires and creates honesty and self-knowledge. 
 
- Trust - Prayer requires and creates both restful trust and confident hope. 
 
- Surrender - Prayer requires and creates surrender of the whole life in love to God.
