The Hexham-born goalkeeper knocked on Pardew's door in the summer asking for a chance to prove himself in the first team.
But with Tim Krul and Rob Elliot ahead of him, he was always clutching at straws, but at least he made the point "I am good enough".
We will find out if he is good enough in the coming weeks.
The 21-year-old goalkeeper is set for a run in Pardew’s side with Tim Krul and Rob Elliot injured.
Alnwick – who came off the bench in last weekend’s 2-1 win over Chelsea after Elliot suffered a thigh tear – will make his full debut in this evening’s game against Arsenal at the Emirates Stadium.
Alan Pardew: “I think Jak knows this is a real game-changer for him.
“It can be seven games, roughly, he might have in that goal, and it’s a great opportunity for him.
“Who knows? After five or six we might be kicking ourselves that we didn’t give him one (a contract). It might have been cheaper!
“The ball is very much in Jak’s court, and that’s where it will stay until such time as the two goalies come back and we make a decision.
“He’s been very good in training.
“Everyone who interviewed him after the game will say he’s a humble guy. He’s got no delusions of grandeur, but he also believes he’s ready.
“Although he’s very young to be goalkeeper of Newcastle, he’s confident he can do the job and lets hope he can.”
