“Conference on spiritual subjects is a most important means of grace. As iron sharpens iron, so does exchange of thoughts with brethren sharpen a believer's soul. It brings down a special blessing on all who make a practice of it. The striking words of Malachi were meant for the Church in every age --‘Then those who feared the Lord spoke often one to another--and the Lord hearkened, and heard it, and a book of remembrance was written before him for those who feared the Lord, and that thought upon His name. And they shall be mine says the Lord, in that day when I make up my jewels.’ (Mal. 3:16, 17.)
What do we know ourselves of spiritual conversation with other Christians? Perhaps we read our Bibles, and pray in private, and use public means of grace. It is all well, very well. But if we stop short here we neglect a great privilege and have yet much to learn. We ought to ‘consider one another to provoke to love and good works.’ We ought to ‘exhort’ and ‘edify one another.’ (Heb. 10:24; 1 Thess. 5:11.) Have we no time for spiritual conversation? Let us think again. The quantity of time wasted on frivolous, trifling, and unprofitable talk, is fearfully great. Do we find nothing to say on spiritual subjects? Do we feel tongue-tied and speechless on the things of Christ? Surely if this is the case, there must be something wrong within. A heart right in the sight of God will generally find words. ‘Out of the abundance of the heart the mouth speaks.’" (Matt. 12:34). From Expository Thoughts on the Gospels on Luke 24 13-20.
