James 5:16 (NKJV)
There are some people who are very skilled at what they do, often these people are professionals in their areas of expertise and they make their living from doing what they are highly specialized in. For example, everyone can count to 10, but some people are specially trained in the areas of finances and accounting. But, while some people are experts in these areas and some are not, you don't have to go to a professional to be able to use a calculator. There are some things that may seem complicated and difficult, but with the right training those things can be done by anyone.
Some Christians seem to have the idea that prayer is a mysterious process that does not work the same for everyone, and someone like a pastor can get prayers answered that others cannot; these people believe that prayer is something only certain Christians can do because they are experts at it. Some people have even told me that they have a special ministry of prayer that others do not have, but there is no ministry of prayer listed in the Bible. Prayer is really just communicating with God, and while some people have developed in the area of prayer more than others, we don't need to be a prayer expert to be effective with our prayers.
James 5 tells us that the effective, fervent prayer of a righteous man avails much. Every righteous person can pray as effectively as any other righteous person, and as Christians we are righteous in Christ. The words "effective" and "fervent" here talking about prayer mean active and efficient. When we pray according to the Word of God we are praying effectively and our prayers are actively working in the areas we pray about. We don't need to look for a prayer expert, God will hear and answer our prayers as quickly as He would anyone else who prays according to His Word. We can all go to God in prayer and be confident that our prayers will work!
