When we don't mean it

Are there times when u said things that u dnt mean it at all. Yupz.. that's wat I did today.. sometimes I wonder why I did that... u know like say things that are not v nice.. or make me sound really skeptical.... and then regret saying it.. cos I think others may feel that I dnt trust him.. or may feel being wronged... well... I must really learn to exercise more self-control and say things tat are edifying and encouraging .. things that will build others up and stop all the stuff that tear ppl down or discourage them... esp when I dnt even mean what I say... It serves no purpose at all... it only creates a gulf between ppl and destroy trust and relationship.

Oh Lord... guard my tongue so that whatever that comes out of it will glorify you.
