Language is the pinnacle feature of every culture. That is why it is so important, vital, and essential that we speak in heavenly tongues. The kingdom of heaven is from above. We are strangers here and are told to be set apart from the world as holy.
Our true culture is from above. The kingdom of heaven has its own languages, customs, and values. Jesus exemplified them during His ministry. When we imitate Jesus, we are walking in kingdom culture. When we speak in tongues, we are communicating with heaven.
You can not be truly apart of another culture unless you can speak the language of that culture. When I first starting learning Chinese, I was so hesitant to use it. If I wanted to order a lunch box, I wasn't sure if they would understand me. To my amazement, once I said the right sounds, they immediately gave me the item I desired.
To them, it was just another customer ordering a lunch box, but to me, it was a revelation of the power of language. Once I speak forth the right words, I put things into motion and what I asked for comes to me. The good news of heaven is that angelic tongues work like this. These tongues are a gift of the Holy Spirit that bring us into heavenly realms and help us to pray when we don't know how to pray.
The Father desires to give us the Holy spirit. We just have to ask in faith and then start speaking out the gifts that belong to Him. When we communicate with heaven, then we pray the Lord's prayer - Your kingdom come, on earth as it is in heaven. Whatever we bind on earth will be bound in heaven. And whatever we loose on earth will be loosed in heaven. This is the benefit and power of speaking in heavenly tongues. We speak the language of heaven, for we are of above, our true home with the Father.
