James 3:10 Out of the same mouth proceed blessing and cursing. My brethren, these things ought not to be so.

Ouch!
But it’s totally true.
I’m guilty of it.
Praising God one moment and then commenting on how rotten the day was.
Remember, God is the creator of each day and we should rejoice and be glad in it.
There is also the extreme view of those that bless God one moment and cuss you the next.
I don’t believe in that behavior but I have known many that claim a relationship with Christ and have a very foul mouth.
James did not believe in it either.
He said, “Does a spring send forth fresh water and bitter from the same opening? Can a fig tree, my brethren, bear olives, or a grapevine bear figs? Thus no spring yields both salt water and fresh.” James 3:11-12
The mouth is hard to control but you are the one that controls yours!
