You are God's masterpiece dear friend. "So God created mankind in his own image, in the image of God he created them; male and female he created them" Genesis 1:27 Because you were created in the image of God you are of great worth.
“God saw all that he made, and it was VERY GOOD!” Genesis 1:31 And that includes YOU friend. You are valuable to him. God showed how valuable you are when He sent his Son to die for you. So the next time you look in the mirror and think about speaking poorly about yourself, remember you are created in the image of God to do good works. Criticizing yourself would be criticizing what God has made. The Lord said that all he made was GOOD! That includes you! Believing or speaking any lie counter to that discounts the truth of God’s Word!
He created you with great intention and He created you for a very specific Kingdom purpose and for you to worship Him and share His Glory with others! If you are here on this Earth then you still have work to do for the Kingdom.
“For you created my inmost being; you knit me together in my mother’s womb, I praise you because I am fearfully & wonderfully made; your works are wonderful. I know that full well!” Psalm 139:13-14
