We notice from Romans 8:32 that the cross of Jesus Christ (God not sparing His Son) is the foundation or basis upon which God does all other things.
"...all the blessings we enjoy as Christian people come to us because of what happened on the cross. The cross is the most crucial event in history. It is from the cross that every benefit ultimately comes."  Martyn Lloyd Jones The following five things are plainly seen from Romans 8:32-36:
1--God "gives us all things" needful for our lives, based upon the foundation of the cross where He did not spare His own Son. In other words, He didn't spare His Son (the best), so He will likewise not withhold any good thing. The cross is the foundation of His promise to provide all we need.--verse 32
2--Christians are above accusation, based upon the work Jesus did on the cross. Jesus Christ was accused of our sin and charged with our guilt, and put to death in our place. Nobody can charge us with any sin because our sins were transferred to God's Son, and then He died for us so no accusation against us will stand.--verse 33
3--Christians will never be condemned. Jesus stood in our place condemned, that we might be free not only from accusation but also from condemnation.
Hallelujah! What a Savior!
Bearing shame and scoffing rude,
In my place condemned He stood;
Sealed my pardon with His blood.
Hallelujah! What a Savior! 
The cross is the foundation for the believer's pardon. There is therefore now no condemnation for those who are in Christ Jesus" (Romans 8:1).--verse 34
4--Christians will never be separated from the love of God. Because Jesus was separated from His Father on the cross, where He suffered and died in our place, we will never be separated from the love of Christ. Jesus will not remove His love from us if we act poorly, just as God did not give us His love because we lived rightly, but rather simply because He chose to do so for the glory of His own Name (Deuteronomy 7:7-8). So tribulation, distress, persecution, famine, nakedness, danger, and sword will not separate us from the love of Christ, and the cross is the basis for this promise of God to never remove His love. This is love without end, amen!
5--Christians will conquer in all things - even in death. Because Jesus died and rose again, thereby defeating sin, death, hell and the grave, Christians are now made "more than conquerors" through Him Who loved us unto death. The cross is the foundation for our triumphing in all things.--verse 37
