Your Spirit Can Pray
Praying in the spirit is one of the dividing lines between charismatic and denominational Christians. The Charismatics have made people feel like if you not praying in tongues, you're not as spiritual as you should be. And some denominations teach their folks that tongues is of the devil. I personally pray in tongues almost daily, for reasons I'll list below. I first want to show you a few passages on the topic.
Walking In the Spirit is Natural
The spirit of God is like unlimited or infinitely high voltage power. If humans were exposed to his direct spirit/power, we would instantly die. His power must be stepped down for us to not die from his presence. Much of my teaching is based on the heart, in this illustration you can look at your heart as the transformer that steps down God's power. Jesus taught this in the parable of the sower. He basically says that you can experience as much of the kingdom as your transformer/heart will allow you to experience. I pray you increase the capacity of your transformer to allow more power to flow!
How to be a King
You are a king and a priest of God's kingdom that shall reign in this life. He has raised you with Christ and seated you in Heavenly places. You are a co-heir of everything Jesus inherited in his resurrection and ascension.
That sounds wonderful, it sounds very spiritual, but what does it mean to you now? Do you actually know how to live within those realities in this present life?
