My honest answer to the title of this post is that I have no idea if Biblical Christians are making a difference on Social Media. From a personal perspective, I have received both an unusually higher level of encouragement from my limited blogging (I have been on somewhat of a hiatus in the last month) as well as an increase in the number of new Christian writers asking for advice.
"Biblical Christian Worldview" is a Ministry, not a Trophy
Finally, we, as Christian bloggers, are not writing about interesting worldly stuff like scientific cutting-edge developments, nor are we playing to the predominantly liberal slant of Medium and Google search algorithms in support of woke culture. This effort is ministry, something He calls all of us to as He brings our skills and abilities in line with His will to share the Good News of Jesus Christ with a lost and dying world. Every Christian reading this post has skills and a gift God desires each of us to use to see the eternal lives of those around us changed, for eternity. Pray that He will give you the courage and conviction to apply those talents in His name. For each of us, the time is short.
Romans 11:29 - For the gifts and the calling of God are irrevocable.
When we get to Heaven we will know then if our efforts as Biblical Christians were used by God, in the areas of Social Media and elsewhere. In the mean time....
2 Timothy 4:5 - As for you, always be sober-minded, endure suffering, do the work of an evangelist, fulfill your ministry.
