Rom. 8:32 He who did not spare his own Son but gave him up for us all, will he not also give us all things with him?

Why did God give us all things?

Gen. 22:2 He said, "Take now your son, your only son, whom you love, Isaac, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I will tell you."

Gen. 22:12 He said, "Do not stretch out your hand against the lad, and do nothing to him; for now I know that you fear God, since you have not withheld your son, your only son, from Me."

Gen. 25:5 Now Abraham gave all that he had to Isaac;

Gen. 22:16 and said, "By Myself I have sworn, declares the LORD, because you have done this thing and have not withheld your son, your only son,
Gen. 22:17 indeed I will greatly bless you, and I will greatly multiply your seed as the stars of the heavens and as the sand which is on the seashore; and your seed shall possess the gate of their enemies.

Rom. 5:8 But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us.
Rom. 5:9 Much more then, having now been justified by His blood, we shall be saved from the wrath of God through Him.
Rom. 5:10 For if while we were enemies we were reconciled to God through the death of His Son, much more, having been reconciled, we shall be saved by His life.

John 3:16 ¶ "For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life.
John 3:17 "For God did not send the Son into the world to judge the world, but that the world might be saved through Him.

Eph. 2:8 For by grace you have been saved through faith; and that not of yourselves, it is the gift of God;
Eph. 2:9 not as a result of works, so that no one may boast.

1John 4:9 By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him.
1John 4:10 In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins.

1Cor. 3:23 and you belong to Christ; and Christ belongs to God.

Gal. 3:29 And if you belong to Christ, then you are Abraham's descendants, heirs according to promise.

God gave us all things because of what Abraham and Jesus did, and how we responded to them.
