Your prayers are all powerful. You don’t have to worry that praying silently in your head will diminish the impact of your prayers. In fact, sometimes silent prayers help quiet your mind and tune into God’s powerful presence with you. I’ve experienced many awe-inspiring moments sensing God’s presence with me during silent prayer. My book Wake Up to Wonder describes one time when I took a break from a stressful workday to pray silently in a local church’s sanctuary that is always open for prayer. The stillness in the church seemed to be embracing me with a sense of peace, which left no room for stress to linger. No other person was there with me, but God’s Spirit was there. As I prayed in my head, the words of Psalm 46:10 came to mind: “‘Be still, and know that I am God.’”
There are certain situations when speaking your prayers out loud makes more sense than praying them in your head. For example, when you’re praying with other believers in order to help each other, it can be especially encouraging to pray out loud so that everyone can hear. Prayer is a vital part of the fellowship of believers within the church. Acts 2:42 records that in early church gatherings, people “devoted themselves to the apostles’ teaching and the fellowship, to the breaking of bread and the prayers” together. You may also prefer speaking prayers out loud when your emotions compel you to do so. Psalm 81:1 urges: “Sing for joy to God our strength; shout aloud to the God of Jacob!” Sometimes you simply feel like praying out loud as a way of emphasizing your enthusiasm, vocalizing your concern, or expressing other types of messages to God.
However, in other situations, it’s most appropriate to pray in your mind. For instance, you may find it’s best to pray silently when you’re in emotional pain. 1 Samuel chapter 1 records Hannah praying in anguish over her infertility. “Hannah was praying in her heart, and her lips were moving but her voice was not heard…” verse 13 says. God answered that prayer in Hannah’s head by giving her a son: Samuel, who grew up to become a faithful prophet and judge. It’s also best to pray in your head rather than pray out loud to draw other people’s attention to your prayers. In Matthew 5:5-8, Jesus reveals that God knows what you need before you even ask, and encourages private prayer: “And when you pray, do not be like the hypocrites, for they love to pray standing in the synagogues and on the street corners to be seen by others. Truly I tell you, they have received their reward in full. But when you pray, go into your room, close the door and pray to your Father, who is unseen. Then your Father, who sees what is done in secret, will reward you. And when you pray, do not keep on babbling like pagans, for they think they will be heard because of their many words. Do not be like them, for your Father knows what you need before you ask him.”
