What did God do after humanity sinned?
After all humanity sinned and came short of God's glory, God did not stop there. He immediately began preparing for the coming of a Redeemer. He justifies sinners freely by His grace through redemption, buying them back, with the required price being the blood of Christ.
Les teaches that Romans 3:23 concludes all have sinned—every human being from Adam on—and come short of the glory of God. But God didn't stop there. He immediately got busy and started preparing for the coming of a Redeemer. Verse 24 then says sinners are justified freely by His grace through the redemption, the whole process of buying us back. That redemption price had to be the blood of Christ, which is unique because it was divine. Les reminds us that Joseph was not the father of baby Jesus; God was, and the blood circulatory system originates with the father, not the mother.
