Unspoken Prayer Requests

Philippians 4:6 says, “Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.”
Have you ever been to church services where a portion of the service is someone taking the prayer requests of the church? There is nothing wrong with the concept of knowing how to pray for one another, but typically, at the end of prayer request, the speaker usually says, “Unspoken requests by the raise of your hands. Let’s all find a place and pray.” Where in the Bible from Genesis through Revelation will you find unspoken prayer requests? Why would God not want us to speak our prayers and ask Him boldly in faith? The spirit of fear has intimidated so many people to link up with likeminded believers who have sustainable prayer lives because they are ashamed of what they are going through, and instead of being insulated through the power and comfort of the Holy Spirit, they are being isolated to think they are the only one facing these certain issues. Out of shame and fear that others will simply gossip about their problems and struggles within their own homes and lives, they simply have “unspoken prayer requests”, and the result is truly ineffective. 
The Apostle Paul said simply to not worry but make our prayer requests known to God. It is not as though God does not know or that He is forgetful. Jesus did not ask people what their need was simply because He was ignorant of the circumstance. He quite frankly knew what was going on. He just wanted the people to whom He was speaking to address their need in a realm and atmosphere for faith so the need could be met in totality. It is not about shying away from a prayer life, but we must boldly coming to the throne of God, knowing who we are to and in Him!
