I totally get this!
When I go to church- whether on a Sunday or at home in quiet time or whilst having fellowship- it is definitely beneficial to be enthusiastic about whatever I sm about to recieve from God.
Another benefit is being ready, willing and compliant to do all God requires of me to do.
Enthusiasm here is defined in being ready to recieve with the express anticipation of being able to give with all my heart, mind and soul.
You have to recieve so you can give. Why not do it with oomph! 😀
Its simple and effective.
I love it.
