FOUL MOUTH = FOUL HEART.

FOUL MOUTH = FOUL HEART.

Ephesians 5:3-4 But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becomes Saints; 4 Neither filthiness, nor foolish talking, nor jesting, which are not convenient (out of character): but rather giving of thanks. (The Believer’s protection against all these sins is the Cross of Christ, and the Cross alone. Keeping the Cross as the Object of one’s Faith guarantees Victory [Gal. 6:14], and for that we are ever to give thanks to God.)

James 3:10-11 Out of the same mouth proceeds blessing and cursing (presents the tongue devoted to uses so different). My Brethren, these things ought not so to be. (If the Lord has His Way in our hearts and lives, they won’t be.) 11 Does a fountain send forth at the same place sweet water and bitter? (Of necessity, this question must be answered in the negative.)

Ephesians 4:29 Let no corrupt communication proceed out of your mouth (let no slander or faithlessness proceed out of your mouth), but that which is good to the use of edifying (does what we are saying buildup or tear down?), that it may Minister Grace unto the hearers (a Blessing). 30 And grieve not the Holy Spirit of God (proclaims the fact that the utterance of evil or worthless words is repugnant to the Holiness of the Spirit), whereby you are sealed unto the Day of Redemption. (This should have been translated, “In Whom you are sealed unto the Day of Redemption.”The Holy Spirit is Himself the Seal God has placed on us.)

If your a cussing Saint (Christian), then you are Cussing sinner that has fallen from God's Grace.
