Hey! rong... PTL!
Jesus learned obedience by the things which he suffered. Heb 5:8 I've often thought, based upon this verse, that by having our memories removed to wipe away our tears and free us from all our sorrows; which allows me to walk in obedience to the Spirit now and keeps me from ever blaspheming the Holy Spirit when we're in the world to come.
Also, the Lord grievously chastens his children that we might be partakers of his holiness. Heb 12:10, 11 When calamity strikes others, I think that the Lord makes the rain to fall on the just and the unjust; but when it happens to me, I consider it to be the Lord's chastening and looking to what needs correction, I trust that the Lord will produce in me the peaceable fruit of righteousness.
As a minister of the gospel, Paul speaks of our rejoicing as he filled up that which is behind of the afflictions of Christ in his flesh for his body's sake, which is the church. Col 1:24 Sobering thought since we too are able ministers of the gospel.
