What bothers me is that somehow the people fighting against us are the ones with the top seats in our own tag. Anyone coming to Medium to look for edification from the Christian section might leave sorely disappointed.
You are right on target here.
Many of those writers who tag their stories Christianity in Medium are actually out to malign true Christianity and undermine the faith of believers.
2 Timothy 4:1-5 (NKJV)
1 I charge you therefore before God and the Lord Jesus Christ, who will judge the living and the dead at His appearing and His kingdom: 2 Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching. 3 For the time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers; 4 and they will turn their ears away from the truth, and be turned aside to fables. 5 But you be watchful in all things, endure afflictions, do the work of an evangelist, fulfill your ministry.
