God bless you brother, I've always thought how there are Christians who get angry easily. Sure, you have to fight with the old man, but sometimes they do nothing to get that old man out of them. The most important thing is to reflect God in our lives, with our testimony, and if there is always bitterness, anger with strong words, shouting ... what example are we giving to the world? What will an unbeliever think of our testimony? Would you like to seek Christ if we show a hostile attitude? ... As you write in your publication, we should be humble towards others and reflect Christ in our lives.
