Prayer is not a means to an end. That is, prayer is not an action one undertakes in order to get a result. Prayer is a goal in itself. Prayer is life with God. The Bible is full of people at prayer. The psalms are known as the Prayerbook of the Bible. Each psalm is a prayer. The Christian tradition is filled with a multitude of witnesses to the power of prayer and the possibility of prayer.
In the Sermon on the Mount, Jesus exhorts the people not to pray on the street corners like the hypocrites but to go into your secret place to pray for your Father who is in secret will hear you there. A vibrant personal prayer life is what many Christians strive for, but most of us feel like we always fall short. John Wesley preferred private prayer as a means of grace, a way that God acts in our life. Another means of grace is corporate prayer, and this is what we do on Sunday morning with the prayers of the people.
We lift up prayers together for two reasons: to intercede on behalf of others, and to remember that we are one body. Intercessory prayer is prayer for another, and when we lift up the names of people on our life who are sick or in need, we collectively ask God to intercede in their lives with healing in grace. This is the first and more obvious reason. The second is just as important. When we voice our prayers, we remember that in the church, truly, the words of John Donne are true, "no man is an island unto themselves." We are connected. When one of our members hurts, we all hurt. Just like when a single part of your body hurts, you hurt. If my feet are hurting, I am hurting. When my sister in Christ is hurting, I am hurting. When my brother in Christ is grieving, I am grieving.
We pray each other's prayers to remember that we are not alone. God is with us. In worship, God is with us. In pain, God is with us. As we pray together, let us not forget our connection to each other and to this world. Lord in your mercy, here our prayers.
