Your worth should be
BY THE WORD OF GOD
Think about where you've been, love where you are, and dream about where you want to be...
1 Samuel 15:22 says obedience is better than sacrifice, which refers to God explaining that he rather have the obedience of his people than their burnt offerings. However, if you allow me to put it in a present-day tense, obeying the instructions of your parents or persons of authority is better than trying to offer a gift to overshadow your wrongdoing. God knows we won't always get it right, which is why he provides us with grace, but we should still have a desire to be obedient. When you are obedient to God, he will do miraculous things in your life.
KNOW YOUR WORTH.
We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ.
II Corinthians 10:5 (New International Version)
