Perhaps a broader reading of Romans is necessary to understand:
Rom 8:26 Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
Rom 8:27 And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.
Rom 8:28 And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
Rom 8:29 For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
Rom 8:30 Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.
Rom 8:31 What shall we then say to these things? If God be for us, who can be against us?
Rom 8:32 He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?
Rom 8:33 Who shall lay any thing to the charge of God's elect? It is God that justifieth.
Rom 8:34 Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.
Rom 8:35 Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?
Rom 8:36 As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter.
Rom 8:37 Nay, in all these things we are more than conquerors through him that loved us.
Rom 8:38 For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
Rom 8:39 Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
I believe the all things He is referring to is not every material thing we would desire as this would only feed the lust of our flesh.
It would seem this chapter focuses on the justification of the body of Christ. Noting that these same ones who have all things worked our for their good are sometimes martyred we can see that heavens idea of what is important and meaningful is a higher standard than a carnal mind would access.
Perhaps the meaning of all things can be brought out by a few other scriptures:
2Pe 1:3 According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue:
2Pe 1:4 Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.
Eph 1:3 Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ:
Eph 1:4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
He has chosen us, sanctified us, justified us, made us righteous, He has made us His sons and given us great spiritual blessing and heritage.
