@jacquelineugwu: “[24] But Jesus did not commit Himself to them, because He knew all men, [25] and had no need that anyone should testify of man, for He knew what was in man.”
John 2:24-25 NKJV
Knowing that people will be people regardless of who they are or what they mean in your life brings a measure of calm and let's you offer grace and make allowances for when they hurt you.
