Formula or plan or pattern takes difficulty out prayer. The LORD Jesus gave the so called Lord's Prayer as a pattern or formula.
From Paul's prayer in Eph 1:15-19, we learn to:
1. Be intentionally thankful to the LORD. God's blessing includes both things that are given to have and things that are kept back from us in order to enhance the blessed life. Like in Eden, the avoidance of the tree of knowledge of good and evil was to preserve life. A child too must be raised with permission to do some things while other things are withheld from them.
We tend to let things that we think are held back from us or not working steal our gratitude to God. As in Eden, Satan specializes in drawing attention to what is disallowed and highlights and offers it as solution to our so called problems.
2. Make mention of others in prayers
3. Pray for the Spirit of Wisdom and Revelation in the knowledge of God.
