We have established that God’s gospel is His response to the problem of sin. This never to be forgotten subject of sin is the fundamental need of the human race. This is what Jesus, the eternal Son of God, was sent to rectify.
How did sin begin?
We are told in the book of Romans that sin was not in the world originally but it entered the world from outside.
“Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all sinned, Romans 5:12”.
To have an answer to this question we need to turn to two Old Testament prophecies.
First of all we will go to Isaiah where we are introduced to a remarkable being called Lucifer. He is a member of the angelic created order who, it seems, led a rebellion in heaven.
“How are you fallen from heaven, O Lucifer, son of the morning! How you are cut down to the ground, you who weakened the nations! For you have said in your heart; I will ascend into heaven, I will exalt my throne above the stars of God; I will sit on the mount of the congregation on the farthest sides of the north; I will ascend above the heights of the clouds, I will be like the Most High. Yet you shall be brought down to Sheol, to the lowest depths of the Pit”, Isaiah 14:12-15.
