Oh my child, don't you know how precious you are? Every year you grow and grow, your body grows, your mind grows, and your heart grows. You're incredible.
Let me put things in a few simple words here:
Your worth is not found in how you look. To be honest, God doesn't care one bit about how you look. Well actually, He does, because He created you uniquely and in a very certain way. Think about it this way: an artist creates many, many different works of art. Not everyone that sees each work will like every single one. Some with appear more attractive to certain people. However, that does not mean that all the rest of the works are ugly. No- there are other people who prefer those ones, even! What I'm saying is, God doesn't consider your worth by how He made you look. He didn't create you thinking "oh, this one is going to be a failure and no one will really care about her" and make you super ugly or something. Everyone is beautiful to Him. You are one of His AMAZING works!
Your worth is not found in what you do, or what you have done.
To be totally honest, everyone has junk in their past that they regret, that they think about all the time, or that they wish they could change or forget about. If God was to measure your worth against what you have done, every single person would be worthless. Maybe you are still falling into a particular sin or stuck in an addiction. You are never too far gone to come back. NEVER. Isn't that just CRAZY AMAZING!??
Your worth is found in Jesus Christ. He loves you- every single part, every brushstroke, every piece. He created you as a PRICELESS work of art, unlike any other work He created. He won't ever run out of things to create! Seriously, what artist does? He is the most famous and most genius artist of all time. Without fail, He creates each of us unique, every single one of us DIFFERENTLY! Let's just take a moment to stand AWESTRUCK at this!
Your worth is found in Christ, who loves you, who sacrificed the life of His own Son to give you life, and who cares for you every single day. Share this with everyone you know; this message is so important.
