You can pray in your head. God hears prayers of tears, sighs, words, groanings, everything.
An ever-present, all-knowing God will hear every word from your mouth, thought in your mind and whisper of your heart.
Paul also has the same idea in Romans 8, as he exemplifies the working of the Holy Spirit in prayer. Even when we pray with our minds, we can pray amiss. But he intercedes the mind of God for us to God whenever we pray, whether in our understanding or mindlessly, so long as we are praying in faith.
There's power in our words so it's important to pray out loud but praying inside your head is okay too because he hears our heart, just not necessarily as much power.
There is nowhere in the Bible where we're told that Satan can read our thoughts, and thus hear our silent prayers. Scripture never states that angels are all-knowing. And if a holy angel isn't omniscient, neither is a fallen one like Satan.
Praying with our eyes open transforms us and aids in making present the Kingdom of God.” This is where our prayer really connects with the real world, when we are moved to action, to concretely sharing the compassion and hope and consolation of Jesus to a world much in need of God's love.
Most prayer is directed to God the Father. Jesus teaches us to pray to the Father, and He prays to the Father throughout His time on Earth (John 16:23 and John 17:1-26). When we are saved, God becomes our Father, too (John 1:12). We can bring any request before Him, and He will hear us (Philippians 4:6).
Encouragingly, there is no biblical reason to believe that praying out loud is more or less effectual than praying silently. We may do either.
One of the biggest keys to hearing God and knowing it's his voice is simple: It's paying attention. Colossians 4:2 tells us being watchful and thankful is an integral part of our prayer conversation. If I'm not watching for God's answer, I can't expect to discern it.
The key is to ensure that our physical posture aligns with the attitude of our hearts. If lying in bed helps us to focus and connect with God, then it is an acceptable and meaningful way to pray. The writings of well-known Christian authors also support the idea that prayer is not confined to a specific posture.
The answer to this is: God hears your prayers on all occasions, whether you're praying out loud or praying silently in your mind. You can be confident that God will hear the prayers in your head as he listens to your inner thoughts.
There is one sin that Jesus says is “unforgiveable,” and that is blasphemy against the Holy Spirit. Jesus says, “And so I tell you, every kind of sin and slander can be forgiven, but blasphemy against the Spirit will not be forgiven.
To pray, you can kneel, stand, lie prostrate, jump for joy. You can pray in any position at any time. The point is to position your heart. Whether on your knees or not.
It makes no difference to God if we pray with a projected voice or if we pray in a whisper. A perfect example of this is Hannah in 1st Samuel 1:13.
The Pattern of Prayer
It's through the Son and in the Spirit. So, it's to the Father, through him the Son, and in the Spirit. You might ask, “Does this mean that it's okay to pray to Jesus?” Answer, yes.
So since the Father is the only true God according to Jesus, it is the Father that Jesus is referring to as the only One whom we should worship and serve. We should all understand what it means to worship and serve someone. To put it simply, it means to obey His every command.
Invoking Jesus' name affirms that our prayers are rooted in Christ, but if we choose not to say it, it does not lessen our confidence that God listens.
End your prayer
Once you've said all that you wanted to say, you can end your prayer by saying, “In the name of Jesus Christ, amen.” We do this because Jesus is the way to connect to our Father in Heaven and all things should be done in His name.
To rest in grace and peace. The best image I can come up with for spiritually free prayer is the image of my own hands, relaxed and open. Open hands indicate that I am not shaking my fist in anger, wringing my hands in fear, grasping for this moment's want, or clinging to the outcome I demand.
We are worshipping a God who isn't limited by our physical actions to hear His children. From this, to close your eyes or not when praying is an individual choice you make as God's child because it doesn't limit Him. Either option you take is not a sin.
