Pray the Perfect Will of God

Solomon, one of the wisest Kings to have ever lived on Earth, wrote about the power of the tongue in this manner:

Death and life are in the power of the tongue, and those who love it will eat its fruit. (Proverbs 18:21)

This verse shows that death does not come only from sickness, old age, accidents and so forth, but from the tongue. The same with life; it comes from the tongue and not human activities.

The verse further states that "those who love it will eat its fruit", suggesting that those who take care of their tongue will enjoy its fruit and those who don't will enjoy its fruit. Therefore, one can use their tongue to either bring life or death.

Go through the following scriptures carefully:
With it (the tongue), we bless our God and Father, and with it we curse men, who have been made in the similitude of God. 10 Out of the same mouth proceed blessing and cursing. My brethren, these things ought not to be so. Does a spring send forth fresh water and bitter from the same opening? Can a fig tree, my brethren, bear olives, or a grapevine bear figs? Thus no spring yields both saltwater and fresh. (James 3:9-11)

Very often, we may have promptings or a leading to pray for something, but we're not certain how to approach the issue. The Holy Spirit, through the speaking of Tongues, helps us formulate our prayers according to the will of God.

Likewise, the Spirit also helps in our weaknesses. For we do not know what we should pray for as we ought, but the Spirit Himself makes intercession for us with groanings which cannot be uttered. Now He who searches the hearts knows what the mind of the Spirit is because He makes intercession for the saints according to the will of God. (Romans 8:26-27)

When we pray in tongues, we are praying the perfect will of God as the Holy Spirit Himself is interceding on behalf of us. Set aside specific times for praying in the Spirit. You will see serious results.
