“Why did Jesus have to die for me, I’m not such a bad person?”

1 John 1:8
"...If we claim to be without sin, we deceive ourselves and the truth is not in us."

Mark 2:17 (Jesus)
"...I have not come to call the righteous, but sinners."
[This does not mean the people who are ‘righteous’ are not called by God, but that unless they recognise that they are sinners too they will not beable to accept Jesus’ sacrifice for their sins since they will not beable to understand it. Such a sacrifice would only mean something to them if they were able to acknowledge that without it they would be lost (the wages of sin is death; the soul who sins is the one who will die)]
