Christ died for you. God sent Jesus Christ to the cross, in order to pay your sin debt and mine in full. When Jesus Christ went to the cross and shed His blood, that was God's way of paying your sins debt and mine in full. You are not worthless to Him!
Too bad the world doesn't understand just how much His grace is worth and the sacrifice it took to provide it! We are only able to comprehend this much and we need to have faith that it's all we need to know!
