For "Whoever would love life and see good days must keep his tongue from evil and his lips from deceitful speech." - 1 Peter 3:10.
The sin of lying, slandering, cussing and abusive language is one that is generally taken lightly by Christians, even preachers. These however stop the flow of God's glory and leave you subtly susceptible to satanic powers. Be holy as God is. Do not allow your lips to sin today. God bless.
