All you have to do is to make a new text document in your scripts folder and copy paste the script.After that rename the text document.txt to Whatever.lua.

Code:
function Buff_Command(event, player, message)
if (message == "#help") then
player:FullCastSpell(54675)
player:FullCastSpell(20217)
player:FullCastSpell(58451)
player:FullCastSpell(48161)
player:SendBroadcastMessage("God helped you!")
end
end
