Laugh now, but in judgment you will not.
1st, you already know He exists as there are enough evidence to convince you of it, but in your unrighteousness surpressed it (Romans 1:18-20)
2nd, He suffered and died for YOU, Jeffrey; to save you from Hell so what possible excuse can you give to a living and angry God (Hebrews 10:31)?
And if you think your good works will outweigh your bad works, think again (Isaiah 64:6)
You're not just going to Hell for the sins many of us think you're committing, but the 10 commandments you're breaking.
There are 613 commandments in the scriptures, not just the 10; break one, you've violated all (James 4:17).
And the worst sin, is when you continue even now, to spit in the face of Jesus who sacrificed Himself for you; the one person who could save you from the Just wrath of God.
