Prayer is the splicing of our limp wire to the lightening bolt of heaven. How astonishing it is that God wills to do His work through people. It is doubly astonishing that He ordains to fulfil His plans by being asked to do so by us. God loves to bless His people. But even more He loves to do it in answer to prayer.
For example, God knew that His purpose was to increase the men of Israel. But He said, “this also I will let the house of Israel ask me to do it for them: to increase their people like a flock.” (Ezekiel 36:37)….
…A pastor who feels competent in himself to produce eternal fruit –which is the only kind that matters- knows neither God nor himself. A pastor who does not know the rhythm of desperation and deliverance must have his sights only on what man can achieve.
John Piper as quoted in brothers we are not professionals
The prayer of a righteous man is powerful and effective.
