Paul wrote this letter as he awaited execution. Despite all that Paul was facing-death, the end of his ministry, abandonment by most of his friends for fear of persecution-he faithfully directed his spiritual son Timothy to the hope that is in Christ. As he exhorted Timothy to boldness, endurance, and faithfulness in the face of false teaching, Paul showed his customary concern for sound doctrine. Scripture, said Paul, is "breathed out by God" and is sufficient in all things pertaining to the faith and practice of Christians (3:16-17). Older believers, therefore, should be eager to pass on their knowledge of Scripture to those who are younger in the faith (2:2). Paul probably wrote from Rome, a.d. 67 or 68 (From ESV Bible).
