Praying in the language of the spirit is not the same as speaking or praying in tongues. Tongues are languages; thus, you might command the Holy Spirit to command your spirit to pray in Japanese, or in Italian, or in Greek. This is a good option if you often have difficulty praying in any language other than in English, or in your native tongue.
In contrast, when you pray in the language of the spirit, and from the heart, you are giving the indwelling Holy Spirit Of God an opportunity to speak your cause to God. The indwelling Holy Spirit will tell him who you are and what you need, how you think and how you feel. He will tell God the condition of your heart, if you pray from your heart.
Prayer in the spirit is an essential component of the life of anyone who is in the millennial kingdom of God. Practice praying in the spirit at least two or three times a day. God will see you, and he will help you to cleanse your heart.
He will heal you when healing is necessary, challenge you when a rebuke is essential to your growth, and state your case before the ether when the ether seeks condemnation for wrongs you did not commit. The Lord God Almighty is El Shaddai. The Lord God Almighty is true, and he is faithful.
