We have it all wrong. Don't change who you are,because of those who just don't appreciate you for who you are. Don't change because they can't see your beauty. There are people who allowed themselves to be bitter, because of the hurts, the pains, people have caused them. But change for the better, not for the wrongs, people have caused. But because God made you, you. He made you kind, sweet, nice. He formed your heart this way. He gave you a heart to love. He made you to care for others.
I had a problem with who I was once. I thought I was too kind, too nice, to compassionate. I began to let the words of people affect me. I allowed people to make me bitter, my heart started closing in on me. I felt defeated. I felt like i wasn't me anymore. My smile was gone. My laughter was gone at one point. My heart began to grow cold. But God had to remind me to remember who I was. He had to show me, this isn't the person he created, he didn't form this. I let myself become a different person. I let my surroundings change me. But I failed to realize my greatness came from just being me, just being genuine, and not allowing jealousy,hate, evil, bitterness, slander, etc. Fill my heart. And the most amazing part of all was finding people that understood who I was. They appreciated and loved me as I was . Even at my worst.
The secret is change for the better, don't change for the worst. We're still expected to not be naive, but to use wisdom, to discern, when to act, when to speak, when to be heard.
So, God is asking you today: do you desire to let the world change you? Will you remain faithful like Joseph, no matter what. He was tempted beyond cause. But he held on to the faith. He was unchanged, he wasn't moved by rain, by hail, by storm. But he kept on. And became great!
Don't let anyone change you... your greatest glory comes from just being yourself.
