People can be cruel. Now that, that has been established how would you handle it if you're a believer or just a person not looking to be tossed and turned by every word someone says about you? IDENTITY, Identity, identity!!! Your very important 3-in-1 word. No one has a right to determine you, but you the only living being that has a right to give you identity is God, our Creator. Our identity is found in knowing him anything else is second rate and more often than not ungodly in nature. People are going to say, you're stupid, lazy, ugly, a waste of space, a looser etc etc BUT who's listening to that when you have a calling and destiny that you're trying to pursue for your own life ? A solidified identity is found in the Word of God which says, Jeremiah 1:5 Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations. God was telling Jeremiah here that he even before he was formed in his mothers womb he knew everything about him that means he also knew His purpose and destiny with Jeremiah.
Man doesn't have all the answers to our questions and we're certainly all learning, for no one knows everything and opinions are certainly what they are. Pray for those that hurt you and speak out against you, that use you, that persecute you and watch the blessings fall in your direction as you gain strength and confidence in God and in your self, that's what God wants he wants us to be confident in Him and in our selves.
