Imagine there's a classmate at school who doesn't like you and keeps making fun of you behind your back. You have two choices: spend all your time trying to convince that classmate you're cool, fighting back, or feeling sad; or keep being honest and kind, do what's right, and let God take care of the situation.
The Bible says that when we live the right way and please God, He Himself works in the hearts of difficult people. It's like having the biggest, most powerful friend in the universe watching out for you behind the scenes!
