What is the point of daily suffering?
That depends upon what type of sufferings you're referring to.
When I'm going through intense trials or sufferings, which is pretty often, btw, Peter's first epistle is one place that I turn to because that seems to be the main theme of that epistle.
Here are some examples:
1Peter 1:3
Blessed
be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead,
1Peter 1:4
To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you,
1Peter 1:5
Who are kept by the power of God through faith unto salvation ready to be revealed in the last time.
1Peter 1:6
Wherein ye greatly rejoice, though now for a season,
if need be, ye are in heaviness through manifold temptations:
1Peter 1:7
That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ:
1Peter 1:8
Whom having not seen, ye love; in whom, though now ye see
him not, yet believing, ye rejoice with joy unspeakable and full of glory:
1Peter 1:9
Receiving the end of your faith,
even the salvation of
your souls.
I think that the key words here are "if need be". In other words, God may need to bring or allow fiery trials into our lives at times in order to purify us in a way that is similar to gold being refined by fire. The fiery trials, in essence, expose the "dross" in our lives that God wants removed. It's been said that "if you can't stand the heat, then get out of the kitchen", but I'd recommend that nobody runs from the fiery trials that God brings or allows our ways. If we refuse to be purified, then I fully believe that God will continue to bring or allow more fiery trials until we finally deal with whatever God is seeking to expose and remove from our lives.
1Peter 2:18
Servants,
be subject to
your masters with all fear; not only to the good and gentle, but also to the froward.
1Peter 2:19
For this
is thankworthy, if a man for conscience toward God endure grief, suffering wrongfully.
1Peter 2:20
For what glory
is it, if, when ye be buffeted for your faults, ye shall take it patiently? but if, when ye do well, and suffer
for it, ye take it patiently, this
is acceptable with God.
1Peter 2:21
For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps:
1Peter 2:22
Who did no sin, neither was guile found in his mouth:
1Peter 2:23
Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed
himself to him that judgeth righteously:
Here, we're told that we've been called to suffer as Christ suffered or to suffer wrongfully. According to Peter, this is both thankworthy and acceptable with God. Peter knew a thing or two about suffering wrongfully.
Acts 5:40
And to him they agreed: and when they had called the apostles, and beaten
them, they commanded that they should not speak in the name of Jesus, and let them go.
Acts 5:41
And they departed from the presence of the council, rejoicing that they were counted worthy to suffer shame for his name.
If you go back and read the account, then you will see that Peter was one of the apostles who was beaten and who rejoiced that he was counted worthy to suffer shame for Christ's name.
1Peter 3:14
But and if ye suffer for righteousness' sake, happy
are ye: and be not afraid of their terror, neither be troubled;
1Peter 3:15
But sanctify the Lord God in your hearts: and
be ready always to
give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:
1Peter 3:16
Having a good conscience; that, whereas they speak evil of you, as of evildoers, they may be ashamed that falsely accuse your good conversation in Christ.
1Peter 3:17
For
it is better,
if the will of God be so, that ye suffer for well doing, than for evil doing.
1Peter 3:18
For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit:
Once more, we see that there may be times that it is God's will that we suffer for well doing or for righteousness' sake. During those times, we need to always be ready to give an answer to those who ask us for a reason for the hope that is in us with meekness and fear. Our hope must always extend beyond this life and towards the life that is yet to come.
1Peter 4:1
Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: for he that hath suffered in the flesh hath ceased from sin;
1Peter 4:2
That he no longer should live the rest of
his time in the flesh to the lusts of men, but to the will of God.
1Peter 4:3
For the time past of
our life may suffice us to have wrought the will of the Gentiles, when we walked in lasciviousness, lusts, excess of wine, revellings, banquetings, and abominable idolatries:
1Peter 4:4
Wherein they think it strange that ye run not with
them to the same excess of riot, speaking evil of
you:
1Peter 4:5
Who shall give account to him that is ready to judge the quick and the dead.
Here, Peter not only tells us to arm ourselves with a mindset that expects sufferings to come, but sufferings which are directly related to our ceasing from sin. In other words, we should fully expect to be shunned by others when we no longer live the type of rebellious lives that they are living. I don't know about anybody else reading this, but I've been shunned by a lot of people for this very reason.
1Peter 4:12
Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you:
1Peter 4:13
But rejoice, inasmuch as ye are partakers of Christ's sufferings; that, when his glory shall be revealed, ye may be glad also with exceeding joy.
1Peter 4:14
If ye be reproached for the name of Christ, happy
are ye; for the spirit of glory and of God resteth upon you: on their part he is evil spoken of, but on your part he is glorified.
1Peter 4:15
But let none of you suffer as a murderer, or
as a thief, or
as an evildoer, or as a busybody in other men's matters.
1Peter 4;16
Yet if
any man suffer as a Christian, let him not be ashamed; but let him glorify God on this behalf.
It took me a while to get there, but I can honestly say that I'm "happy" when I suffer as a Christian or when I am reproached for the name of Christ. In fact, I get worried when I'm not suffering some sort of persecution because that normally means that I'm hiding my light under a bushel at that time.
As far as suffering for righteousness' sake is concerned, it's impossible not to...unless we're not living righteously.
Sorry for such a long post, but, like I said, suffering seems to be the main theme of Peter's first epistle, and it's helped to get me through many a rough time.
