Out of all the gifts that I have received in life, the gift of praying in tongues(or praying in the spirit) has been the best and most beneficial gift in my life. Jesus promises us the Holy Spirit and it's even foretold in the book of Joel 2:28 that in the last days after Israel is forgiven by God he begins to tell Joel how he is going to bless and restore them. One way is by pouring out his spirit. In a world full of increasing deception and sin, the Holy Spirit is needed in the life of every believer. There are many benefits that come with praying in the Spirit:

To name a few:1. A deeper understanding of God's word2. Able to overcome Temptations3. You're filled with a supernatural power4. You will go into intercessional groanings and pray for others without them telling you anything5. You are being built up in the spirit or "edified" (to withstand hard times)

If you desire this gift, know that you can be filled! This is not just a gift for a few, but to all who desire and believe, you too shall be filled.
