What if I'm not good enough?

We know God said in His word, ALL have sinned and come short of His glory. This means that ALL mankind has sinned and stands before Him GUILTY and WITHOUT EXCUSE. What does God say about sin and it's penalty?

Rom 6:23 (KJV): For the wages of sin is death...

James 1:13-15 (KJV): Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man: But every man is tempted, when he is drawn away of his own lust, and enticed. Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.

2 Pet 2:4-6 (KJV): For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment; And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly; And turning the cities of Sodom and Gomorrha into ashes condemned them with an overthrow, making them an ensample unto those that after should live ungodly;

Rev 20:15 (KJV): And whosoever was not found written in the book of life was cast into the lake of fire.

Luke 12:2-5 (KJV): And I say unto you my friends, Be not afraid of them that kill the body, and after that have no more that they can do. But I will forewarn you whom ye shall fear: Fear him, which after he hath killed hath power to cast into hell; yea, I say unto you, Fear him.
