In the book of Proverbs it is written, “Where there is no guidance, they fall like leaves; salvation exists in much counsel” (Prov. 11:14). Can you see here the power of the Word, brothers? Can you see that what the Holy Scripture is teaching us? It safeguards us, so that we do not trust ourselves, so that we do not consider ourselves wise, so that we do not believe that we can guide ourselves. We need assistance. After God Himself, we need our guides.
2 Peter Chapter 1
18 And this voice which came from heaven we heard, when we were with him in the holy mount.
19 We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts:
20 Knowing this first, that no prophecy of the scripture is of any private interpretation.
21 For the prophecy came not in old time by the will of man: but holy men of God spake [as they were] moved by the Holy Ghost.
The Lord has provided some as teachers, some as prophets, and some as preachers of the Word – cf 1 Corinthians 12:28-29. In the Divine Scripture therefore we are instructed that we cannot make understanding of scripture on our own. As such, even the more difficult is it for us to save ourselves, as Abba Dorotheos exhorts above – we need spiritual guides. For this reason our Lord has given us the teachers, the Apostles (literally those who were sent), and Prophets, preaching the Word to us and helping us to understand. Not only must we study Sacred Scripture, but we must also inscribe it upon our hearts. It is for this cause that the Lord has gifted us with the Saints, who lived the words of the Gospel and that they could guide us into the knowledge of the Truth.
