It's all over the Bible.

Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:

By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God.

And not only so, but we glory in tribulations also: knowing that tribulation worketh patience;

And patience, experience; and experience, hope:

And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us. - Romans 5:1-5

But what things were gain to me, those I counted loss for Christ.

Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ,

And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith:

That I may know him, and the power of his resurrection, and the fellowship of his sufferings, being made conformable unto his death;

If by any means I might attain unto the resurrection of the dead. - Phillipians 3:7-11

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;

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. - 1 Peter 4:1-2

Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you:

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.

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.

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.

Yet if any man suffer as a Christian, let him not be ashamed; but let him glorify God on this behalf.

For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God?

And if the righteous scarcely be saved, where shall the ungodly and the sinner appear?

Wherefore let them that suffer according to the will of God commit the keeping of their souls to him in well doing, as unto a faithful Creator. - 1 Peter 4:1-19

Only let your conversation be as it becometh the gospel of Christ: that whether I come and see you, or else be absent, I may hear of your affairs, that ye stand fast in one spirit, with one mind striving together for the faith of the gospel;

And in nothing terrified by your adversaries: which is to them an evident token of perdition, but to you of salvation, and that of God.

For unto you it is given in the behalf of Christ, not only to believe on him, but also to suffer for his sake;

Having the same conflict which ye saw in me, and now hear to be in me. - Phillipians 1:27-30

These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world. - John 16:33

James, a servant of God and of the Lord Jesus Christ, to the twelve tribes which are scattered abroad, greeting.

My brethren, count it all joy when ye fall into divers temptations;

Knowing this, that the trying of your faith worketh patience.

But let patience have her perfect work, that ye may be perfect and entire, wanting nothing. - James 1:1-4

Blessed are they which are persecuted for righteousness' sake: for theirs is the kingdom of heaven.

Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.

Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you. - Matthew 5:10-12

From that time forth began Jesus to shew unto his disciples, how that he must go unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be killed, and be raised again the third day.

Then Peter took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be unto thee.

But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.

Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me.

For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it.

For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul? - Matthew 16:21-26

Much of it is also implicit, like when Jesus says that you are blessed if you are hungry, poor, or hated, because your reward in heaven will be great. Suffering is what allows you to appreciate the things of God. That's not to say that you should pursue suffering, just not resent it if it happens. If you are rich or well fed, it is tempting to think all your needs are met, and that you don't need God. When you are suffering though, God is all you have to rely on. The world and God are at odds, so it stands to reason that if you want to know God you have to reject the things of this world, but for that you will be hated and punished by the world. If you are rewarded by the world, it is likely because you have rejected the things of God, and will be rejected by him in the end. Anyway, you don't have to agree, I'm just putting some thoughts out there. And I'm not a Jesuit. I don't follow any denomination.
