The clean tongue of a Christian is not:
- Foul mouth
- Lashing out
The tongue of a child of God is controlled by the Spirit of God.
Ephesians 4:29…Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
The reason for clean communication? The heart is made clean in the new birth. Made clean by the power of God’s Grace. The abundance of a clean heart is a clean tongue as taught by the Lord Jesus Christ.
Matthew 12:34…for out of the abundance of the heart the mouth speaketh.
Therefore the verbal witness is vehicle for God – to win others to Christ.
