There is no real formula for prayer and it is done in the context of an overall relationship with the Lord.
But within prayer there is a call to understanding and contemplation of what the Lord is about and what meaning is brought forth in the prayer relationship.
What could be a missing link in the prayer relationship and what might be brushed over as understood yet not really contemplated in the meaning of prayer?
One missing link is acknowledgement of God as the creator in the here and now for you and me.
For example if you want healing in prayer, for example healing of the eyes, or eyesight problems, the prayer might be that you would thank and understand that God created your eyes and all eyes and the physical structures involved in sight and he does create the ongoing ability for you to see both in the physical sense and the spiritual sense.
As the Lord creates the clouds that pass by in the sky, he also creates and continues to create the visual field that enables you to see these changing clouds or sights in the sky that are also created by him on an ongoing basis.
However your eyes are functioning or not functioning, the sight provided is similar to the way sight is provided to all those who have the eyes to see and one can contemplate that God is the creator of sight.
But this is only one example and anything we can think of that can be asked for specifically can be contemplated as involving the creative presence and power of the Lord in the here and now.
For example, the weather we encounter in a given day is indeed a creation of the Lord and we can involve ourselves in this creation by asking for specific types and forms of weather, requests that have been made and have been answered according to the Bible. Anything we might desire on the material plane still has to manifest itself in the creative reality of the forming future.
The prayer for healing can be contemplated as involving creation. You are asking the Lord to create a situation of health and the maintenance of health.
A relationship situation and a work situation can be understood as involving the creative presence of the Lord.
There is the theory of evolution and the missing link. The subject manner of prayer is often the case of direness and of the quality of last resort. However in prayer we are staring in the face of creation with our requests and it is important to acknowledge and understand that creation itself can and should be contemplated within the deeper recesses of prayer requests and in a sense we go to creation in our prayer requests.
Truly there is no other place to go for an ongoing creative presence for the help that we need.
