Take God at His Word and act on it. He had provided the gift of the Holy Spirit for you. The following prayers will help encourage you in establishing your heavenly language.
Heavenly Father, I am a believer. I am Your child and You are my Father. Jesus is my Lord. I believe with all my heart that Your Word is true.
Your Word says if I will ask, I will receive the Holy Spirit. So in the Name of Jesus Christ, my Lord, I am asking You to fill me to overflowing with Your precious Holy Spirit. Jesus, baptize me in the Holy Spirit.
Because of Your Word, I believe that I now receive and I thank You for it. I believe the Holy Spirit is within me and, by faith, I accept it.
Now, Holy Spirit, rise up within me as I praise God. I fully expect to speak with other tongues, as You give me the utterance.

Father, You said in Your Word, "If ye then being evil, know how to give good gifts unto your children: HOW MUCH MORE shall your heavenly Father give the Holy Spirit to them that ask him?" (Luke 11:13). I’m asking You to fill me with the Holy Spirit. Holy Spirit, rise up within me as I praise God. I fully expect to speak with other tongues as You give me the utterance (Acts 2:4). In Jesus’ Name. Amen!
Begin to praise God for filling you with the Holy Spirit. Speak those words and syllables you receive—not in your own language, but the language given to you by the Holy Spirit. You have to use your own voice. God will not force you to speak. Don’t be concerned with how it sounds. It is a heavenly language!
