After you've invited Jesus Christ into your heart, you are now born-again. You can be filled with the Holy Spirit and power with the evidence of speaking in other tongues. You can receive your prayer language in the same way you received Jesus—by faith and by simply yielding to Him. You receive in your spirit, not your head.
God's perfect will is for every believer to be filled with the Holy Spirit and power. He will give you the power to live right, pray right, do right, and be a witness.
“You shall receive power after that the Holy Spirit is come upon you: and ye shall be witnesses unto me.”
You would like everything that God has for you, right? Of course you do. We all do.
Put your hand on your belly, and say this with your heart and your lips out loud:
Now open your mouth and speak it out. Start speaking forth those heavenly syllables. It comes from your belly, not from your head.
Jesus said, “He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.”
I command those rivers to flow right now. Be filled with the Holy Spirit and Fire, in Jesus' mighty Name, Amen.
You can pray in your heavenly language as you get ready for the day, as you drive to and from work or school. The more you pray in tongues, the more you are built up and strengthened. The more you pray in tongues, the more you hear the voice of the Spirit. When you don't know what to pray or how to pray, pray in tongues. When you pray in tongues, you edify yourself—you bless yourself, and build yourself up spiritually.
