Maybe your Bible story in Sunday School is a healing miracle, and you're really keen that the children understand: it's because of who Jesus is! It shows us he's the Son of God!
Remember Peter suddenly realising who Jesus is in Matthew 16 (like Mark 8)? "You are the Christ - the Son of the living God" (Mt 16:16) - that's what we're supposed to realise, when we've seen the miracles. Some did - Blind Bartimaeus understood, and called out to Jesus "Jesus, Son of David, have mercy on me!".
"One Man Said" imagines what it must have been like to be healed by Jesus, and, like Blind Bartimaeus, realise exactly who Jesus really is. "One man said: 'He gave me sight when I was so blind, now I can see in the bright sunshine, who could this be with this power so good?' Gave him sight? SON OF GOD!"
There are 4 verses - three miracles, and one verse about our response. Actions / Motions are fairly easy to work out for this one!
