Let me suggest another reason: In order to grow in the wisdom of God’s word and to better understand and articulate its Truth.
Consider 2 Timothy 2:7 with me. Paul writes, “Think over what I say, for the Lord will give you understanding in everything.” This verse has two parts. First, is the command to “think over what I say”–in other words, to cogitate, to meditate, and to postulate on the inspired words of the living apostle. Enlisting the imagery of a soldier, an athlete, and a farmer in previous verses to respectively illustrate devotion, honesty, and rigorous labor, the elder apostle seems to indicate the value in thinking hard upon the his apostolic message (cf. 2:2). Certainly, the apostle Peter considered some of Paul’s words very challenging (2 Pet. 3:15-16), and thus these truths needed then and still require careful and thoughtful attention. For this reason alone, blogging is useful because it stimulates thought.
In addition to this plain command comes the second part of the verse which underscores a foundational principle, “the Lord [gives] understanding.” This command to think in verse 7 is coupled with the biblical the reality that the Spirit of Christ must illumine truth (cf. John 16:13; 1 Cor. 2:14-16; 1 John 2:27). This means that hard thinking alone does not produce revelation. The story of Martin Luther teaches us this. The Augustinian monk beat on Romans 1:17 until Paul was a bloody mess, but not until the Spirit moved did the apostle speak and divulge his secrets of justifying fatih.
This dual reality, then, is humbling and refreshing truth. Humbling because mankind is absolutely dependent on divine revelation; refreshing because God graciously reveals himself to those who earnestly seek him (Jer. 29:11; Matt. 7:7). Consequently, blogging when done well, perhaps even done “spiritually,” is an exercise in biblical cogitation which can and should promote a humble cry for help in ascertaining God’s truth. Likewise, in expressing these truths in open conversation allows for more precise application and proclamation in a sin-darkened world. Of course, thing like personal hubris, vanity, and self-deceit stand in the way of this aim, but without compromise this must be the kind of blogging to which we endeavor–the kind that thinks hard and prays for wisdom in our choice of words. Paul knew this dual reality, so did Solomon (see below). Think hard about it and ask the Lord, “Do you?”
May the Lord give us grace to see our blindness.
My son, if you receive my words
and treasure up my commandments with you,
2 making your ear attentive to wisdom
and inclining your heart to understanding;
3 yes, if you call out for insight
and raise your voice for understanding,
4 if you seek it like silver
and search for it as for hidden treasures,
5 then you will understand the fear of the Lord
and find the knowledge of God.
6 For the Lord gives wisdom;
from his mouth come knowledge and understanding;
7 he stores up sound wisdom for the upright;
he is a shield to those who walk in integrity,
