Before anything else, God loves you all the time. Doing the right thing does not buy his love or guarantee a present.
Imagine a friend at school saying, "Tell the teacher you saw me return the library book." You did not see that happen. You do not need to guess what happened. You can simply say, "I didn't see it. Let's check together."
A good friend can help look for the book or speak to the teacher. You do not have to say you saw something you did not see. If your friend keeps pushing you, ask a teacher or another trusted adult for help. You do not have to solve the whole problem by yourself.
Sometimes you may repeat something and later learn it was wrong. Tell a trusted adult what you know so they can help put it right. You are not responsible for a trick someone played on you.
Jesus did what was good, even when people tried to trap him. He loves you and helps you take the next honest step.
