Thank you for the "ABC's of Christianity" and your presentation of the Gospel.

So God created mankind in his own image, in the image of God he created them; male and female he created them. Genesis 1:27

Originally, mankind was supposed to be the image-bearer of God. That image was marred by sin and man was separated from God.

Jesus answered: "Don't you know me, Philip, even after I have been among you such a long time? Anyone who has seen me has seen the Father. How can you say, 'Show us the Father'? John 14:9

The Son is the image of the invisible God, the firstborn over all creation. Colosians 1:15

Jesus came as the "Last Adam" to both restore mankind's relationship to God and to restore the marred image of God by His perfect life and character.
