I believe this is the section you refer to.
If you'll ask me why I went to Africa, I'll tell you I went primarily to improve on the justice of God. I didn't think it was right for anybody to go to Hell without a chance to be saved. So I went to give poor sinners a chance to go to heaven. Now I haven't put it in so many words, but if you'll analyze what I just told you do you know what it is? Humanism. That I was simply using the provisions of Jesus Christ as a means to improve upon human conditions of suffering and misery. And when I went to Africa, I discovered that they weren't poor, ignorant, little heathen running around in the woods looking for someone to tell them how to go to heaven. That they were MONSTERS OF INIQUITY !!! THEY WERE LIVING IN UTTER AND TOTAL DEFIANCE OF FAR MORE KNOWLEDGE OF GOD THEN I EVER DREAMED THEY HAD!
They deserved Hell! Because they utterly refused to walk in the light of their conscious, and the light of the law written upon their heart, and the testimony of nature, and the truth they knew! And when I found that out I assure you I was so angry with God that on one occasion in prayer I told Him it was a mighty ...... little thing He'd done, sending me out there to reach these people that were waiting to be told how to go to heaven. When I got there I found out they knew about heaven, and didn't want to go there, and that they loved their sin and wanted to stay in it.
I went out there motivated by humanism. I'd seen pictures of lepers, I'd seen pictures of ulcers, I'd seen pictures of native funerals, and I didn't want my fellow human beings to suffer in Hell eternally after such a miserable existence on earth. But it was there in Africa that God began to tear THROUGH THE OVERLAY OF THIS HUMANISM! And it was that day in my bedroom with the door locked that I wrestled with God. For here was I, coming to grips with the fact that the people I thought were ignorant and wanted to know how to go to heaven and were saying "Someone come and teach us", actually didn't want to take time to talk with me or anybody else. They had no interest in the Bible and no interest in Christ, and they loved their sin and wanted to continue in it. And I was to that place at that time where I felt the whole thing was a sham and a mockery, and I had been sold a bill of goods! And I wanted to come home.
There alone in my bedroom AS I FACED GOD HONESTLY WITH WHAT MY HEART FELT, it seemed to me I heard Him say, "Yes, will not the Judge of all the earth do right? The heathen are lost. And they're going to go to Hell, not because they haven't heard the gospel. They're going to go to Hell because they are sinners, WHO LOVE THEIR SIN! And because they deserve Hell. BUT, I didn't send you out there for them. I didn't send you out there for their sakes." And I heard as clearly as I've ever heard, though it wasn't with physical voice but it was the echo of truth of the ages finding its' way into an open heart. I heard God say to my heart that day something like this, "I didn't send you to Africa for the sake of the heathen, I sent you to Africa for My sake. They deserved Hell! But I LOVE THEM !!! AND I ENDURED THE AGONIES OF HELL FOR THEM !!! I DIDN'T SEND YOU OUT THERE FOR THEM !!! I SENT YOU OUT THERE FOR ME ! DO I NOT DESERVE THE REWARD OF MY SUFFERING? DON'T I DESERVE THOSE FOR WHOM I DIED?"
And it REVERSED IT ALL! AND CHANGED IT ALL! AND RIGHTED IT ALL! And I wasn't any longer working for Micah and tens shekels and a shirt. BUT I WAS SERVING A LIVING GOD! I was there not for the sake of the heathen. I was there for the Savior that endured the agonies of Hell for me, who didn't deserve it. But He deserved them. Because He died for them.
Do you see? Let me epitomize, let me summarize. Christianity says,"The end of all being is the glory of God." Humanism says, "The end of all being is the happiness of man."
And one was born in Hell, the deification of man. AND THE OTHER WAS BORN IN HEAVEN, THE GLORIFICATION OF GOD! And one is Levite serving Micah, and the other is a heart that's unworthy serving the living God, because it's the highest honor in the universe.
WHAT ABOUT YOU?
What about you? Why did you repent? I'd like to see some people repent on Biblical terms again. George Whitefield knew it. He stood on Boston Commons speaking to twenty thousand people and he said, "Listen sinners, you're monsters, MONSTERS OF INIQUITY! You deserve Hell! And the worst of your crimes is that criminals though you've been, you haven't had the good grace to see it!" He said, "If you will not weep for your SINS and your crimes against a Holy God, George Whitefield will weep for you!" That man would put his head back and he would sob like a baby. Why? Because they were in danger of Hell? No! But because they were MONSTERS OF INIQUITY, that didn't even see their sin or care about their crimes. You see the difference? You see the difference? The difference is, here's somebody trembling because he is going to be hurt in Hell. AND HE HAS NO SENSE OF THE ENORMITY OF HIS GUILT !!! AND NO SENSE OF THE ENORMITY OF HIS CRIME !!! AND NO SENSE OF HIS INSULT AGAINST DEITY !!!
