Thanks for sharing your concerns and questions! You are not alone! I grew up in a Protestant, evangelical church and have had a fervent, growing faith for years upon years. I have not converted to orthodoxy, but have been attending an orthdox Church for the past few months. I go to seek a greater way to worship, but often find myself challenged especially when I pray. Whether at Church or at home...I fear my words are too much or too little...I try to pray with a prayer book but yearn to cry out to God with my own words. In my prayer times, I often do both...but am scared that when I do pray with my own words that I am doing it all wrong. This feeling has caused me, at times, to not want to pray at all. This is never the answere.
If your situation is at all like mine, I want to encourage you to keep praying. I will not claim to know all the answeres...or even to be firm where I stand in my faith. I do know that our God is a relational God who gave us prayer as a way to communicate with him. As you seek truth, your honest intentions will be rewarded...seek and ye shall find.
Keep praying sunny!
