Never under estimate the power of a prayer. At times, we need to look outside of ourselves to see how God works His wonders. We tend to concentrate too much on our needs (humanly speaking) without realising the spiritual need that God is fulfilling in each of us every moment. We tend to think that our prayers, to be fulfilled, has to be met in our conditions, yet God’s thoughts is not ours to fathom. And in His great mercy, He doesn’t meet our conditions but always provide us our specific needs.
To be used by God to help others is not a cause for us to boast but it is humbling and unworthy of us to play a part in salvation’s history and what a grace that He finds us to do His will.
Even if we disregard the prompting of the Spirit, the other’s prayer will be answered in His ways beyond what we can imagine. Yet to be able to follow the prompting of the Spirit is not by our own strength but that which the grace that God gives us, the heart that He molds and moves.
All prayers are effective as God hears them and He moves heaven and earth to fulfil His will.
