In a context where the Lord invites all people to join themselves to Him, he invites them into his house which will be know as a house of prayer (Isaiah 56.7). He will accept the prayers of his people and give them joy as they worship the Lord.
This primary purpose for the house of the Lord has unfortunately and sadly been neglected in most churches of today. If you are seeking fellowship as it is called in most churches and by most believers then you will hit gold. If you desire good food, you will be filled. If you long for programs that will scratch where you itch, look no more. Incredible effort is given to provide whatever you need, especially in larger churches.
However, if you are looking for a place where people are committed to prayer, where prayer is more than an attachment to whatever else is being done for whatever reasons, you will be looking and searching for sometime. The reason is simple. For many leaders and even pastors, prayer is cultural not biblical or Scriptural.
We pray because, after all, that's what Christians are supposed to do. We pray because we think that by praying we can get what we need. We don't pray because it the lifeline we have between sinful man and a holy God. We just do it for brief moments and move on.
Praying was never meant to be an attachment. God's house is to be a house of prayer. No wonder Jesus was upset when he encountered people who had turned it into a den of robbers (Matthew 21.13). As noted, prayer was not to be an attachment, but rather, the primary activity of God's people.
What this might mean for us is a critical question for believers longing to be the people God has called us to be. Prayer certainly isn't limited to having a room in your church designated for prayer. No, the entire house is to be a house of prayer. This has to mean that the people who make up the church are people of prayer.
