His Son and His apostles all teaching a heart of repentance caused by Christs' sacrifice which brings forgiveness. That heart comes from seeing how the Son of God was terribly sinned against, yet continued loving those who hated Him.
Substitutionary (or penal) atonement is contrary to all scripture.
On the contrary, it is precisely what is stated throughout Scripture:
Isa 53:4 Surely he has borne our griefs and carried our sorrows; yet we esteemed him stricken, smitten by God, and afflicted.
Isa 53:5
But he was pierced for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his wounds we are healed.
Isa 53:6 All we like sheep have gone astray; we have turned—every one—to his own way; and
the LORD has laid on him the iniquity of us all.
Isa 53:7 He was oppressed, and he was afflicted, yet he opened not his mouth; like a lamb that is led to the slaughter, and like a sheep that before its shearers is silent, so he opened not his mouth.
Isa 53:8 By oppression and judgment he was taken away; and as for his generation, who considered that he was cut off out of the land of the living,
stricken for the transgression of my people?
Isa 53:9 And they made his grave with the wicked and with a rich man in his death, although he had done no violence, and there was no deceit in his mouth.
Isa 53:10
Yet it was the will of the LORD to crush him; he has put him to grief; when his soul makes an offering for guilt, he shall see his offspring; he shall prolong his days; the will of the LORD shall prosper in his hand.
Isa 53:11 Out of the anguish of his soul he shall see and be satisfied; by his knowledge shall the righteous one, my servant, make many to be accounted righteous, and
he shall bear their iniquities.
Isa 53:12 Therefore I will divide him a portion with the many, and he shall divide the spoil with the strong, because he poured out his soul to death and was numbered with the transgressors;
yet he bore the sin of many, and makes intercession for the transgressors. (ESV)
Mat 1:21 She will bear a son, and you shall call his name Jesus,
for he will save his people from their sins.”
Mat 27:46 And about the ninth hour Jesus cried out with a loud voice, saying, “Eli, Eli, lema sabachthani?” that is, “My God, my God, why have you forsaken me?” (ESV)
Luk 22:19 And he took bread, and when he had given thanks, he broke it and gave it to them, saying, “
This is my body, which is given for you. Do this in remembrance of me.”
Luk 22:20 And likewise the cup after they had eaten, saying, “This cup that is
poured out for you is the new covenant in my blood. (ESV)

Was it not necessary that the Christ should suffer these things and enter into his glory?” (ESV)
Joh 1:29 The next day he saw Jesus coming toward him, and said, “Behold, the Lamb of God, who takes away the sin of the world! (ESV)
Joh 3:14 And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up,
Joh 3:15 that whoever believes in him may have eternal life.
Joh 3:16 “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
Joh 3:17 For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. (ESV)

lay down his life for his friends. (ESV)
Act 2:23 this Jesus,
delivered up according to the definite plan and foreknowledge of God, you crucified and killed by the hands of lawless men. (ESV)
Rom 5:8 but God shows his love for us in that while we were still sinners,
Christ died for us.
Rom 5:9 Since, therefore,
we have now been justified by his blood, much more shall we be saved by him from the wrath of God.
Rom 5:10 For if while we were enemies
we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life.
Rom 5:11 More than that, we also rejoice in God through our Lord Jesus Christ,
through whom we have now received reconciliation.
Rom 5:12 Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned—
…
Rom 5:15 But the free gift is not like the trespass. For if many died through one man's trespass, much more have
the grace of God and the free gift by the grace of that one man Jesus Christ abounded for many.
Rom 5:16 And the free gift is not like the result of that one man's sin. For the judgment following one trespass brought condemnation, but
the free gift following many trespasses brought justification.
Rom 5:17 For if, because of one man's trespass, death reigned through that one man,
much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ. (ESV)
Rom 8:32 He who did not spare his own Son but
gave him up for us all, how will he not also with him graciously give us all things? (ESV)
2Co 5:14 For the love of Christ controls us, because we have concluded this: that
one has died for all, therefore all have died;
2Co 5:15 and
he died for all, that those who live might no longer live for themselves but for him who for their sake died and was raised.
…
2Co 5:21
For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God. (ESV)
Gal 3:13 Christ redeemed us from the curse of the law
by becoming a curse for us—for it is written, “Cursed is everyone who is hanged on a tree”— (ESV)
Php 2:8 And being found in human form, he humbled himself by
becoming obedient to the point of death, even death on a cross. (ESV)
Col 2:13 And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him,
having forgiven us all our trespasses,
Col 2:14
by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross. (ESV)
Heb 13:11 For the bodies of those animals whose blood is brought into the holy places by the high priest
as a sacrifice for sin are burned outside the camp.
Heb 13:12
So Jesus also suffered outside the gate in order to sanctify the people through his own blood.
Heb 13:13
Therefore let us go to him outside the camp and bear the reproach he endured. (ESV)

sent his Son to be the propitiation for our sins. (ESV)
Rev 1:5 and from Jesus Christ the faithful witness, the firstborn of the dead, and the ruler of kings on earth. To him who loves us
and has freed us from our sins by his blood (ESV)
And any father who thinks it just to kill the innocent for the guilty is an evil maniac and that goes 70 x 7 for God.
Then, you have some very wrong and evil thoughts about God that you need to repent of. The issue is this:
Rom 6:23 For
the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord. (ESV)
God set out the terms of payment in the OT sacrificial system, as I've shown above--blood is needed to make atonement for sins. If God didn't pay the penalty for our sins, then we must pay it. If he didn't pay it and doesn't require us to pay, then he is not just, and is not God.
Besides, you've missed many other verses:
Joh 10:15 just as the Father knows me and I know the Father; and
I lay down my life for the sheep.
..
Joh 10:17 For this reason the Father loves me, because
I lay down my life that I may take it up again.
Joh 10:18 No one takes it from me, but
I lay it down of my own accord. I have authority to lay it down, and I have authority to take it up again. This charge I have received from my Father.”
Gal 2:20 I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God,
who loved me and gave himself for me. (ESV)

and gave himself up for us,

1Ti 2:5 For there is one God, and there is one mediator between God and men, the man Christ Jesus,
1Ti 2:6
who gave himself as a ransom for all, which is the testimony given at the proper time. (ESV)
The Son did it willingly out of love; the Father did not force him.
“To focus on Jesus as just an example is to reduce him from sovereign Savior to ethical coach and to transform the gospel into law. That Jesus can't help you.”—Timothy Keller
