I agree there is no biblical issues with consuming Coke. It’s just a personal choice.
A major problem we have now is that people don’t fear God. They know what the Bible says about homosexuality but they just ignore it. They ignore it, try to dilute it, or deny it. There will come a day.
It is not an easy challenge, but it is a challenge that, in principle, and according to much evidence in practice too, the gospel can conquer.
