Holding back what we think is an area of weakness for many of us. We can often without malice, feel the need to say what we think. We have to train ourselves to know when to speak and when to keep silent. Some people are clever enough to understand our weaknesses and may try to bait us to gain a reaction.
We have to understand when we are being tested, what to respond to and what things to ignore. Overtime we get better at ignoring and practicing a time to keep silent. It is our peace that the devil is after and our ability to remain calm and choose not to react.
The tongue is a hard thing to tame and although small can do significant damage. For every kind of beast and bird, of reptile and sea creature, can be tamed and has been tamed by mankind, but no human being can tame the tongue. It is a restless evil, full of deadly poison. (James 3:7-8) We have the power to build each other up with what we say and the same ability to tear down. This is why Paul warns us to bless and curse not. (Romans 12:14)
Our daily prayer should be that God will help us to be at peace with others and to hold our peace. To daily understand when to speak and when to keep silent.
