As a former marijuana smoker for the better part of a decade I can atttest to a portion of this article. While you are on marijuana you definitely have no motivation. HOWEVER, this article does not at all take into consideration the regenerate power of our Savior and God so on the other hand I take offense to the article as well. I am now a proud husband, father of 2, and leader in the church just a short 5 years removed from my past life and all of that is because of the aforementioned regenerate power. The Lord continues to work on some memory loss I have suffered, but I am confident I can be productive for the Kingdom even if I don't get that back. I just had to throw in my two cents.
The reason why boils down to the fact that we all are depraved sinners who have fallen short of the glory of God. The fact is that we all have a little "killer" in us but its only bu the grace of God that the killer doesn't show up.
Here is a reason. How about the worsening birth implosion. If we continue down this path to let people of the same gender get married compounded with the womb to tomb policies that are in affect there wont be any people left. Here is another reason if we overturn DOMA (defense of marriage act) and we redefine marriage where does it end? What is next? Will we allow people to marry animals in the next 50 years? That sounds absurd, but just 30 years ago this gay marriage nonsense seemed absurd. Just something to think about. I personally always use these reasons before I use the Biblical reasons (though those are perfectly valid reasons considering they are FROM GOD HIMSELF!!!)
