First argument: God said, I can eat any herb because Genesis 1:29 says briefly, “Behold I have given you every herb to you, it shall be for meat.”
But what about toxic plants or poison mushrooms?
Eating any herb in Genesis 1 was before the fall.
After the fall, sin corrupted the plants and creation.
Second argument: Marijuana is better than pharmaceuticals.
So what? In any health decision you make, are there alternatives besides sketchy meds and marijuana to protect your testimony? When a lost soul sees you smoke, does it appear to be sober?
Titus 2:6 warns, “Young men, be sober-minded.”
1 Thessalonian 5:22 warns, “Abstain from all appearance of evil.”
Is your testimony more important than help?
Revelation 12:11 says briefly, “And they overcame him by their testimony and they loved not their lives unto the death.”
