The midfielder started England's 1-0 friendly win over Denmark on Wednesday, but the 23-year-old is concentrating on maintaining his form for his club before he looks toward representing his country in Brazil this summer.
"I'm playing with a lot of confidence and I'm loving playing football at the minute," Henderson told the Liverpool Echo. "Things have been going well for Liverpool and to get another call-up for England gave me a boost as well. Hopefully I can keep going for the rest of the season.
"It would mean everything to me to go to the World Cup and represent my country. First and foremost, I need to do a job for Liverpool. I'll give my all between now and the end of the season. If I do that then I will have a good chance."
Five Liverpool players started Wednesday’s game at Wembley, with Raheem Sterling, Daniel Sturridge, Glen Johnson and captain Steven Gerrard joining Henderson in Roy Hodgson's side.
And the former Sunderland man believes such recognition is a testament to Liverpool's progress under Rodgers.
"It shows you how well we have done this season," Henderson added. "We are all working really well together and linking up brilliantly. We have to try to bring that into the England setup as much as we can."
