Some people let go of trainings, thinking they’ve gotten the desired results. Before long, they begin to carry even more of the “baggage” than they previously had. So it is spiritually. Hebrews 12:1 says, “…let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us.”
Just make sure you keep praying, speaking in tongues and always, waiting on the Lord! “Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.” (1 Corinthians 9:24-25).
The 5th Chapter of How To Pray Effectively Volume 1, gives a detailed account on the subject of praying in tongues.
