The epistles to Timothy and Titus are not addressed to churches, nor were they to be communicated to the churches as such. Of course the church of God has them, guiding us as to the individual conduct which is an unceasing obligation for Christians.
Timothy had been charged insist on sound doctrine. However he has to draw attention as to the right order in the church. The first letter gives us the order of the church under normal conditions; 2 Timothy, shows us the path of faith when things are abnormal – in disorder.
You have in 1 Timothy 3:15 the principle of Timothy’s conduct.
In 2 Timothy Paul was at the close of his career, and though the church had fallen into disorder, there is no other epistle in which he insists so much on the unfailing courage and energy of the saints. He calls upon them to endure the afflictions of the gospel according to the power of God. We do not have the outward church connected with the body of Christ, but simply individual piety and devotedness wherever he could find it.
Chapter 2:18-22 is indicative of the tone of the instruction as regards the state of the church. The faith of some had been overthrown, so he refers first to the sure foundation of God, the Lord knowing them that are His. Whoever names the name of the Lord is to depart from iniquity. That is individual responsibility. Then he takes the great house as the analogy of the church publicly, showing that in such there are vessels to dishonour, and to be a vessel to honour, a man has to purge himself from these. Then he is to follow righteousness, etc., with those who call on the Lord out of a pure heart. This distinguishes those who are really saints. Paul associates himself with them, and warns of perilous times in the last days – a form of godliness denying the power. He insists, besides his personal authority, upon the known scriptures as a child might read them, and asserts that they are sufficient to make us wise unto salvation, through faith in Christ Jesus. They have been given by inspiration of God, and are adequate to make the man of God perfect [or complete, fit], thoroughly prepared for undertaking all good works.
