Scriptures Referenced in This Episode:

“For everyone has sinned; we all fall short of God’s glorious standard.” Romans 3:23 (NLT)

“12 Sin came into the world because of what one man did, and with sin came death. This is why everyone must die—because everyone sinned…

15 But God’s free gift is not like Adam’s sin. Many people died because of the sin of that one man. But the grace from God was much greater; many people received God’s gift of life by the grace of the one man, Jesus Christ....

17 One man sinned, and so death ruled all people because of that one man. But now those people who accept God’s full grace and the great gift of being made right with him will surely have true life and rule through the one man, Jesus Christ.” Romans 5:12, 15, 17 (NCV)

Organelle: “Little organ.” Organelles are little things inside our tiny cells that have very important jobs to do. They are like our cells' own organs.

Molecule: A creation made from very specific tiny pieces called atoms hooked together.

Information: Information tells us something. It can remove uncertainty, or remove what we don’t know by helping us understand something. It is learning and knowing.

RNA: A molecule that copies information from DNA and brings it to the ribosome printers.

Protein: Molecules in our bodies that create cells and perform many important jobs.

Inherited: Something is passed down and given to someone.

Sin Nature: Our inheritance of sin from Adam and Eve’s first sin. Sin is a part of who we are as humans.
