Though small in size, our tongue has great power and influence. It can lead in the right direction, but can lead in the wrong direction as well. It has the ability to build others, but can also be an instrument of destruction. However, the tongue is still submissive to the heart. For the mature believer, the tongue is tamed by the Holy Spirit. However, those who do not believe in Christ or those who are spiritually immature allow the tongue to run wild and do the work of evil.
