No one can come to me unless the Father who sent me draws him, and I will raise him up on the last day.

The first recorded mention of this truth in the Bible...

Genesis 3:8-10.  Then the man and his wife heard the voice of the LORD God walking in the garden in the breeze of the day, and they hid themselves from the presence of the LORD God among the trees of the garden.

9. But the LORD God called out to the man, “Where are you?”

10. “I heard Your voice in the garden,” he replied, “and I was afraid because I was naked; so I hid myself.”
