"All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness; that the man of God may be perfect, throughly furnished unto all good works." 2 Timothy 3:16-17
On all subjects connected with our most holy faith, it is most desirable to have clear views. Every point of divine truth is laid down with the greatest clearness and precision in the word of God. The darkness, the ignorance, the confusion which prevent us from seeing it are all in us. But as we search the Scriptures, as we meditate upon them, as we by prayer and supplication draw light, life, and wisdom out of Him "in whom are hidden all the treasures of wisdom and knowledge;" and, above all, as we mix faith with what we read, there is often, if not usually, a gradual breaking-in of light; and as we follow up its heavenly rays, it shines more clearly and broadly, and the truth stands out more fully and prominently before our eyes. This is the only way in which we can be "filled with the knowledge of God's will in all wisdom and spiritual understanding," and thus be established in the faith, abounding therein with thanksgiving.
To understand the scripture, to see in it the mind of the Holy Spirit, to be deeply penetrated with, and inwardly possessed of the heavenly wisdom, holy instruction, and gracious revelation of the counsels and will of God unfolded therein, demands much and continual patient and prayerful study. As in business, diligence and industry lead on to prosperity and success, and sloth and idleness are the sure road to ruin; so in the greatest, most serious, and important of all business, the concerns of the soul, there is a holy diligence, a heavenly industry, whereby it thrives and grows, and there is a slothful indolence whereby it becomes clothed with rags (Proverbs 23:21).
