The Key to Effective Prayer


A burdened pastor was sitting at his desk wondering what to do about the large debt on the church building when a stranger came in to see him. The stranger asked if the report about the large debt was correct. When the pastor confirmed the news, the stranger laid a blank check on the pastor’s desk with a simple instruction. The pastor was to fill in the necessary amount and the man would come back later to sign it. The pastor sat there looking at the check. He appreciated the man’s generous impulse but was certain he had no concept of the size of the remaining debt. Finally, he hesitatingly wrote in half of the amount – afraid even that would startle the stranger when he returned. Shortly after this, the stranger returned. He hardly looked at the check as he signed it and quickly left without another word. The pastor looked at the signature and recognized it was the signature of a well-known philanthropist who could easily have paid the whole debt. So often when we pray, we treat God the way that the pastor treated the stranger. We appreciate His sincerity in offering to help us but doubt His ability to really deal with the enormity of the situation as it appears from our perspective. Mark 9:14-29 shows us both this tendency and the cure. Study the passage to learn about the key to effective prayer and how to make it your own.



Before studying God's Word, ask Him to help you understand what He wrote and how He wants it to change your life today.

    This is the first time of Bible study with you. More than once I have been brought to tears. I thought I had faith, belief and confidence but this study has shown me I lack in all. I love my Heavenly Father and my Beautiful Saviour but there is far more to just believing
    I look forward to more study. This studying is going to help me so much in learning and putting “into practice” Gods word. In fighting spiritual battles. Thankyou
