You say, "I think there is merit in tempering our comments" but all I see in the comments is the quoting of Scripture. So how do you suggest they "temper" their comments? In fact, the Scriptures that are quoted aren't even about believers who are struggling with sin but are about the positive power of the gospel. Again I ask, how should you suggest that be 'tempered." And please explain "why" the commenters above should not exhort one another with God's Word — especially when they are using the Word accurately.

Consider Hebrews 3:13 But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin. 14 For we have come to share in Christ, if indeed we hold our original confidence firm to the end. 15 As it is said, “Today, if you hear his voice, do not harden your hearts as in the rebellion.” 16 For who were those who heard and yet rebelled? Was it not all those who left Egypt led by Moses? 17 And with whom was he provoked for forty years? Was it not with those who sinned, whose bodies fell in the wilderness? 18 And to whom did he swear that they would not enter his rest, but to those who were disobedient? 19 So we see that they were unable to enter because of unbelief.

Concerning the believers who are struggling with sin, I think the best thing they could hear is that confidence is possible and is gained through the continual washing of the Word. I think the worse thing they could hear is someone like Tony Jones who thinks that his doubt is virtuous, beautiful and good. And you, my friend, need not be afraid to exhort the "many believers" you must know who are doubting. I have dealt with such believers for 29 years and I have never met one who really wanted any of us to "temper" our exhortations. Instead, they longed for shepherds who relentlessly spurned them unto righteousness.

Consider this brother. God bless.

…which proves that it is Tony Jones that is the hoax and the total crock.

And he gave the apostles, the prophets, the evangelists, the shepherds and teachers, to equip the saints for the work of ministry, for building up the body of Christ, until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, so that we may no longer be children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in deceitful schemes. (Ephesians 4:11-14)

The gospel is the word of truth, and it bears fruit in faith, hope and love.
