In this crazy adventure called life there will be people who surround you, build you up, and empower you to be the person Christ has called you to be. There will also be people who make assumptions about you and create an opinion about you without ever consulting you to find out who you truly are. This may be caused by jealousy or a situation that you were once involved in with them. It hurts to know people are speaking badly about you to others and that they attempt to get people to have the same opinion of you.
I have some good news. The most important thing is that God does not see you the way that person sees you. God does not make assumptions, He knows your heart and He knows your intentions. The people who truly love you in this world won't make assumptions, they see the good in you as well. Define yourself by the way God views you; you are His child; gifted, graceful, and loving. That person is spreading these lies in attempt to bring you down, don't let them have that power over you.
If you have made assumptions about another person try to spend time with them to truly get to know who they are. If the assumptions you had are true it's not your job to spread that, remember the truth will ALWAYS come out.
Love God & Love Others
