That's like saying, "If it takes you ten drinks to get drunk, you're one tenth drunk." Therefore, you're implying that one tenth drunk is sin.
But there's no such thing as one tenth sin. It's either sin or it isn't. If you're right, then Jesus Himself was guilty of sin. So were the apostles. God recommended alcohol. (Deut 14:29; Prov. 31) Was He guilty of sin?
By your logic it's sin for me to eat a Big Mac. Here's why. If I got really hungry and ate 10 Big Macs, I'd be guilty of the sin of gluttony. If I eat one Big Mac, I'm a one tenth glutton which, by your logic, is sin.
Your logic may be, well, illogical.
And you are implying that 7/8 drunk is ok??? And like I said, who determines when you are drunk???
I could weave all over the road in my car and still be sober, according to me...
The verses I posted showed the results of drinking alcohol...The picture painted does not put consuming alcohol in a good light...
