Blogging can be a difficult arena to proclaim the truth. Since there are so many bloggers, I believe every Christian blogger should thoughtfully consider why they should blog, whether they are adding anything profitable to what is being said, and whether what they say honors the gospel and brings glory to Christ.
When that happens, there are times that truth must be defended. If someone publicly defames Christ, there may come a time when they are publicly denounced. That is where every child of God must approach the confrontation with sincerity, humility, and a renewed mind. Anytime the flesh steps in, it is time to take a break, consider deleting a post, posting a contraction or apology, and then turning toward God out of a heart and desire for repentance. If there is no qualification to teach, then that blogger should reconsider the specific nature and purpose of their blog.
At times, Paul had to defend his ministry because of false teachers, and so did Timothy. So, where there are false accusations, stand firm for the truth. Where there is need for better communication, listen and speak diligently to the truth. Where there is need for repentance, confess your sin first to God, and then to those you have wronged so that you might be healed. Consider writing personal resolutions pertaining to your blogging and read over them weekly so that you do not stray from that which you have endeavored to do.
Blogging can be a helpful medium for the proclamation of the gospel, and we need shining lights among the dark and dreary landscape of blogging that too often screams against the truth and the gospel. Commit to pray before you blog. Commit to study before you blog, and if a time comes that you write something that stirs controversy because of truth, do not let anyone hijack your blog in order to snuff out that truth!
