Man’s “tongue potential” is for both blessing and cursing things of God.
But the tongue can no man tame; it is an unruly evil, full of deadly poison. Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God. (James 3:8-9 KJV)
Every man talks out of both sides of his mouth. On one side he blesses God and from the other he curses the things of God. This is a natural phenomenon because of nature of sin which rages and wars in our flesh us as we sojourn in this world.
Our tongue naturally wields a deadly verbal poison left unbridled in our life. Man, left to his own natural devices, often chooses to use his tongue as a spiritual bat swinging wildly through life. Sometimes man swings and misses but often he connects sending ungodly comments hurling out of his mouth geared towards being hurtful and spiritually unproductive towards others. Mankind’s natural speech serves the god of this world; applying the supernatural power from God allows fruitful works of God to flow from a bridled tongue.
God does give mankind spiritual tools to subdue or soften his tongue from the raging nature of sin. This involves allowing divine control from the supernatural power of God rather than fluctuating back and forth between governance in their limited strength along with relying upon God’s power in a “back-up mode.” Man, who has allowed sin to impede his relationship with God, elevates himself to “help” in governing his tongue. It takes supernatural power from God to properly tame the tongue.
Putting on the holiness of God by consecrating our speech to glorify and honor God serves to shed wickedness and darkness of the god of this world from continuing to invade our speech and actions as man walks along the narrow pathway.
Consecration unto holiness is a lifetime process and the thorough taming of the tongue is not possible this side of Heaven but God’s power living in us supernaturally restrains our speech bringing honor and glory unto Him in swift progressive spiritual fashion as we live in obedience to Him.
