Paul's Last Letter
God has made known His will, and it is folly for man to question that which has gone out of His lips.
Ministers of the gospel sometimes do great harm by allowing their forbearance toward the erring to degenerate into toleration of sins and even participation in them. Unfaithful to their trust, they lead astray those who look to them for spiritual guidance. Many among both ministers and people are trampling under their feet the commandments of God. Thus the Creator of the world is insulted, and Satan laughs in triumph at the success of his devices.
Paul's life was an exemplification of the truths he taught, and herein lay his power.
I am appointed a preacher, and an apostle, and a teacher of the Gentiles. For the which cause I also suffer these things: nevertheless I am not ashamed: for I know whom I have believed, and am persuaded that He is able to keep that which I have committed unto Him against that day.
2 Timothy 1:11,12
After speaking of the scene of his trial before Nero, the desertion of his brethren, and the sustaining grace of a covenant-keeping God, Paul closed his letter by commending his beloved Timothy to the guardianship of the Chief Shepherd, who, though the undershepherds might be stricken down, would still care for His flock.
