A number of charismatics pray in another language, that is their prayer language but are yet to fully take advantage of it as they should. This is because they have not been taught what to do when they pray in the Spirit. To some, it is just a sign of baptism but they fail to realize it is an advantage in their walk with the Lord.
At first, I want to let you know that you can interpret your own tongues by looking into your spirit for promptings received while praying in tongues. The promptings, direction or burden in your spirit as you pray in other tongues is the interpretation of your tongues.
Now, this requires patience and practice as it doesn't just happen in one day. This dimension is only open to those that are consistent in praying in tongues almost daily not those who do it occasionally.
Gloria Copeland says she decided to pray in the Spirit daily and it has made all the difference in her life and ministry. That is my story as well. You need to pray consistently in tongues to be able to discern or pick signals in your spirit about what the Lord is saying. You don't rush in and rush out.
Sometimes, when you pick a signal in your spirit while praying in tongues, you continue in prayers for a length of time to be clear about what the Holy Spirit has dropped in your spirit. Until it becomes so clear and strong, you don't stop praying in tongues neither do you act on it. You may have to pray repeatedly for days until clarity comes.
You see, praying in the Spirit clears a pathway for our spirit to become receptive to what the Spirit of God is saying or might want to say. Most of the directions I have received came by praying in the spirit. The more I pray, the stronger they become in my spirit. That's the secret of clarity.
Sometimes, while preparing for a meeting, I receive word of knowledge ahead while praying in the spirit. Even If I forget, the Spirit will impress it upon my heart again while ministering. That is one of the secret of operating in the prophetic accurately. It takes prayer labour and sensitivity.
As you pray in the Spirit, watchout for promptings or impressions in your spirit. That is how to take advantage of this divine blessing.
