Ought Not to Be This Way

James 3:7-12
7 For every species of beasts and birds, of reptiles and creatures of the sea, is tamed and has been tamed by the human race. 8 But no one can tame the tongue; it is a restless evil and full of deadly poison. 9 With it we bless our Lord and Father, and with it we curse men, who have been made in the likeness of God; 10 from the same mouth come both blessing and cursing. My brethren, these things ought not to be this way. 11 Does a fountain send out from the same opening both fresh and bitter water? 12 Can a fig tree, my brethren, produce olives, or a vine produce figs? Nor can salt water produce fresh.
NASU

Action: How should I control my speech to produce only blessings to God and men?
