Praying in tongues has everything to do with your becoming prepared and qualified for your particular calling

Praying in tongues has everything to do with your becoming prepared and qualified for your particular calling. And as you pray in tongues, the Holy Spirit is able to build into your heart the understanding ofGod’s will for your personal lives.

Praying in other tongues also supplies the power to overcome character flaws — those deep-seated character traits that keep cropping up and robbing you of your stamina and initiative to overcome in the face of the common testings and trials that precede almost every major victory and promotion by God.

Praying in tongues always affects you in a positive way. God says that it edifies you (1 Cor. 14:4). In Jude 20, He says that it builds you up on your most holy faith. As you faithfully spend time praying in tongues, your lives begin to be transformed. The Word of God begins to come alive as you place your spirit, the “candle of the Lord” (Prov. 20:27), in the hands of the expert Illuminator.

As you spend time praying in tongues, the Holy Spirit is fast at work doing what He does best: edifying you and putting to death all the things that would hinder you from reaching your full potential. Eventually, He is able to get you to a place where He can take the emphasis off of your own edification and release His power through you on the behalf of others.
