One of the attributes of God is that of longsuffering.
Exodus 34:6 And the LORD passed before him and proclaimed, The LORD, the LORD God, merciful and gracious, longsuffering, and abounding in goodness and truth,
Romans 9:22 What if God, wanting to show His wrath and to make His power known, endured with much longsuffering the vessels of wrath prepared for destruction....
I can only suggest that he wants his children to develop same mind, holding fast to the hope set before them. Paul wrote:
Colossians 3:12 Therefore, as the elect of God, holy and beloved, put on tender mercies, kindness, humility, meekness, longsuffering;
Paul endured a great deal of suffering as a result of his preaching and, in the end, was executed.
2 Corinthians 11:25-30 Three times I was beaten with rods; once I was stoned; three times I was shipwrecked; a night and a day I have been in the deep; 26 in journeys often, in perils of waters, in perils of robbers, in perils of my own countrymen, in perils of the Gentiles, in perils in the city, in perils in the wilderness, in perils in the sea, in perils among false brethren; 27 in weariness and toil, in sleeplessness often, in hunger and thirst, in fastings often, in cold and nakedness— 28 besides the other things, what comes upon me daily: my deep concern for all the churches. 29 Who is weak, and I am not weak? Who is made to stumble, and I do not burn with indignation? 30 If I must boast, I will boast in the things which concern my infirmity.
The writer to the Hebrews draws attention to the suffering of God’s prophets:
Hebrews 11:35-40 And others were tortured, not accepting deliverance, that they might obtain a better resurrection. 36 Still others had trial of mockings and scourgings, yes, and of chains and imprisonment. 37 They were stoned, they were sawn in two, were tempted, were slain with the sword. They wandered about in sheepskins and goatskins, being destitute, afflicted, tormented— 38 of whom the world was not worthy. They wandered in deserts and mountains, in dens and caves of the earth. 39 And all these, having obtained a good testimony through faith, did not receive the promise, 40 God having provided something better for us, that they should not be made perfect apart from us.
James, in his epistle, wrote:
James 5:10,11 My brethren, take the prophets, who spoke in the name of the Lord, as an example of suffering and patience. 11 Indeed we count them blessed who endure. You have heard of the perseverance of Job and seen the end intended by the Lord — that the Lord is very compassionate and merciful.
Suffering in our allotted lifespan is relatively short when set against a future eternity of divine nature promised to those who believe and obey the gospel.
It will all be forgotten when we awake to eternal life.
I hope you find this helpful.
