Hi Mike,
Don't go into one
but I have taught a few lessons on the sheep and the goats and the goats are the people who say they are Christians but do not actually put Jesus teachings into practice.
Basically it is that 'not all who call me Lord Lord will enter heaven', anyone can say they are a Christian, but you actually have to prove it by doing good deeds. Jesus said stuff like when you feed the least of your brethern you feed me, or words to that effect. The Sheep are the people who look upon some unfortunate person and see Jesus in them and help them. Mother Teresa was once asked how she could pick up a total stranger who was covered in blood and sick, take them to a safe place and wash and feed them. She replied that what she saw lying in the gutter wasnt a stranger, what she saw was Jesus lying in the gutter and that was her inspiration.
Mother Teresa was a sheep, people who simply claim that they are Christians and do not put Jesus teachings into action are the goats.
Brian.
