Please help! Movie about a priest/pastor or religious man who hears the voice of god telling him to kill his son or the world will end

If anyone can help I’d be so grateful. I’m sure I watched this film on a major streaming platform, so I am super confused that despite hours of searching I cannot find it anywhere online. 

So this film must be an obscure one, but I remember a LOT of details since this film really stuck with me.

it is essentially a modern retelling of Abraham and Isaac. A man (I thought a priest or pastor) has his first child. He then hears the voice of god telling him to kill his child or the world will end. He is given a deadline. He is experiencing massive grief and conflict as he doesn’t believe god would ask this of him, but equally he believes in god so feels this could be real. He talks to someone above him at the church who agrees that god would never ask that of him and suggests he sees a dr. The movie is quite slow and from my memory there’s basically him spiralling for the rest of the film until the end. He doesn’t kill the child and the deadline passes. The ending is ambiguous, with a blackout occurring outside.

It’s not frailty of seventh sign. It’s not gritty or dark, it’s mostly set in a clean light toned house. For some reason I think they also live by the sea? 

I for some reason was certain the title was Noah or another biblical boys name, but that hasn’t brought up anything.

Thank you if you are able to help.
