Think positive
Put on a brave face
Put your best foot forward
Do not waver

Do not speak of death
and it will not happen
Do not look upon the cross
and it will not crush you

Look on the bright side
Think positive
Do not waver
Jesus

Then Jesus began to teach his disciples that the Son of Man must undergo suffering and be rejected by the elders, and the chief priests, and the scribes, and be killed, and after three days rise again. He said all this quite openly. And Peter took him aside and began to rebuke him. But turning and looking at his disciples, he rebuked Peter and said, ‘Get behind me, Satan!’
