They came to him and said, "Teacher, we know you are a man of integrity. You aren't swayed by men, because you pay no attention to who they are; but you teach the way of God in accordance with the truth. Is it right to pay taxes to Caesar or not? Should we pay or shouldn't we?"
But Jesus knew their hypocrisy. "Why are you trying to trap me?" he asked. "Bring me a denarius and let me look at it." They brought the coin, and he asked them, "Whose portrait is this? And whose inscription?"
"Caesar's," they replied.

Then they asked further,"What belongs to God?"
Jesus answered by questioning them,"Whose portrait are you bearing?"
God has His stamp on you. He has stamped his divine eternal image on you. Though sin marred it, God cleaned it through the blood of His Son. You are worthy because God made you so. Not by your own judgement or action to know your own worthiness. It's only through God's eyes, you, me, and everyone else, is worthy; valuable; precious.
Our own judgement plays big part in forming our own understanding of ourselves but it's not the ultimate and final appraisement. You are worthy because of 1) God's eternal image is on you, 2) Christ's blood has cleansed you.
