"With Jerry we worked during two call-up sessions before the Gold Cup last year and now he has done well enough to maybe play his first international match against Venezuela," Rueda said.
Colombian Rueda has included Bengtson in a 19-man squad of home-based players to begin World Cup preparations with the friendly in San Pedro Sula next Wednesday.
The match is Honduras's last before they leave for Germany on May 15 for a training camp prior to travelling to South Africa for the finals starting on June 11.
Bengtson, 23, plays for first division side Vida and is the Clausura championship's leading scorer with 11 goals.
"I was really surprised by the call but it's my (teenage) son Juan who's been sending messages (to the mobile company), he won it," Rueda said.
"It's a blessing from God," added Rueda of the prize that includes Honduras's Group H matches against Spain, Switzerland and Chile.
Honduran football federation spokesman Edwin Banegas said: "(Rueda) has said he wants to take his family to the World Cup and with this ticket he can at least take his son."
