The most important doctrine in Christianity. If you get GOD wrong, you get EVERYTHING wrong. It matters more than you know. Even and especially if you aren't a Christian.

Father, Son and Holy Spirit.

Genesis 1:26-28
King James Version
26 And God said, Let us make man in OUR image, after OUR likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.

27 So God created man in his own image, in the image of God created he him; male and female created he them.

28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
