It is a spiritual aspect in the lives of Christians to crucify (kill/death) the desires and works of the flesh. God is showing you what is happening in this person’s life whom you have a brotherly love for. The relationship between you and him is emphasized. Which is a relationship of the love of a brother and a father. Your relationship will be an important factor in this person’s life.
There is coming an end (death) of a season of uncleanness or sexual sins, self-righteousness, violent aggressiveness, sins etc.. (dog). This a positive outcome.
