I am naturally a reserved person and most people think I'm a quiet person. I've learnt to be slow to speak and quick to listen.(James 1:19). Ecclesiastes 5:2 tells us our words should be few. Jesus said in Matthew 12:36 that for every idle word men speak, they shall give an account of it on judgement day.For by words shall men be judged and by words shall men be justified.
Proverbs 10:19 says in a multitude of words there's sin but he who refrains his lips is wise. Your prayer should always be for God to set a watch before your mouth and guard the door of your lips. (Psalms 141:3).
