sda

One who believes in the doctrines of the seventh day adventist church. They follow christ as their example, who died for them. His death has the most meaning in their lives. Started by Christ himself, his followers look to him for guidance, whether in sorrow, or in mercy. This faith has a large denomination, and glorifies Christ, and his Creator up above.

all SDAs strive to go to church.

Man, he is a real SDA

SDFIL

SDFIL means (Last name that starts with S) Dont Fall in Love. It is a proven fact that anyone with a last name that begins S doesnt fall in love.

Smiths dont fall in love (SDFIL) because Papa Smith has been married 3 times.
