Jesus said that wherever there is 2 or more gathered in prayer, there He is among them. Does that mean He is absent if I'm alone? Also, what is an 'empty' prayer? There have been times where I seem to be talking to a wall and there are times where I can feel His presence. What's the difference? Most often, I pray in my natural language because when I have prayed using tongues, I am not 100% certain that I actually have my Spiritual language yet and maybe just mimicking what I have heard from others using their tongues. I look forward to your replies, thank you.
