Paul's letter to Timothy reminded him that God's word restores believers back to God. The Spirit's message clearly stated this in the following manner, "...(It is) profitable...for correction (and) for instruction in righteousness."
These two phrases identify the Scripture's extent in restoration. First, it corrects. In its literal meaning, this term describes restoring something to an upright state or setting something right.
In spiritual application, then, the Bible gives correction or improvement in life and character. It corrects from error, disciplines in disobedience, and develops faith. Second, God's word instructs in righteousness. It imparts admonition, training, and education through commands, warnings, and reproof.
No wonder, then, Paul by the Spirit followed this counsel with the direction to preach the word (2 Timothy 4.2-4). The word of God would sanctify the believers with the truth and correct them (John 17.17).
In like fashion, believers and the Church of Jesus Christ today need the sanctification of the Scriptures. With rare exception, the Child of God in this era neglects the Bible and its restoring message. No revival will ever occur without faithful adherence to the truths of Scripture in life and practice.
It refines you unto Godliness.
To demonstrate the effect of Scripture, the Holy Spirit through the Apostle identified its end purpose: to refine the Child of God unto completion and good works.
The revelation of God in His word identifies what mankind is to believe and what to do. Through its application, the Holy Spirit brings mankind into conformity to God's will in thought, purpose, and action. His word cultivates the mind and morals to increase virtue. It edifies the soul by correcting sin and curbing passions (Psalm 119.11).
As in Timothy's day, the Church of Jesus Christ desperately needs these results. She has become selfish, hypocritical, and deceitful. The faithful preaching and application of Biblical truth will engender spiritual revival in the Church, which She so desperately needs. No spiritual revival ever occurred in history without a proper regard for the Scriptures. These simple declarations disclose fundamental truths to believe about God's word. They provide correction from doctrinal error and direction for life.
Spiritual decline always results from the failure to submit to the Scriptures. It inevitably causes unbelief and disobedience. It places mankind's personal authority above the authority of God and His word. David, the Psalmist, stated it clearly in Psalms 119:11: "Thy word have I hid in mine heart, that I might not sin against thee." To those who follow this instruction, it works.
I pray that the Holy Spirit has shown you the necessity of applying these Biblical truths to your life. Only the Spirit of Truth can reveal them to you. Only He can carry them out in your life. May He come to you in grace and bring a spiritual transformation in your life today.
