3:10 {4} But thou hast {b} fully known my doctrine, manner of life, purpose, faith, longsuffering, charity, patience,
(4) So that we are not deceived by such hypocrites, we must set before us the virtues of the holy servants of God, and we must not be afraid of persecution which they suffered willingly, and which always follows true godliness. But we must especially hold fast the doctrine of the apostles, the sum of which is this, that we are saved through faith in Christ Jesus.
(b) You thoroughly know not only what I taught and did, but also how I thought and was inclined.
3:10 Thou hast fully known my doctrine. Thou didst follow my teaching (Revised Version). Timothy had known his teaching and manner of life, and followed it.
3:10-13 The more fully we know the doctrine of Christ, as taught by the apostles, the more closely we shall cleave to it. When we know the afflictions of believers only in part, they tempt us to decline the cause for which they suffer. A form of godliness, a profession of Christian faith without a godly life, often is allowed to pass, while open profession of the truth as it is in Jesus, and resolute attention to the duties of godliness, stir up the scorn and enmity of the world. As good men, by the grace of God, grow better, so bad men, through the craft of Satan, and the power of their own corruptions, grow worse. The way of sin is down-hill; such go on from bad to worse, deceiving and being deceived. Those who deceive others, deceive themselves, as they will find at last, to their cost. The history of the outward church, awfully shows that the apostle spake this as he was moved by the Holy Ghost.
