It would make it hard to enjoy the dinner. Sometimes the little misfortunes of life can take the wind out of or sails. This is particularly true of sin in our life. Jesus by his death and resurrection has purchased bountiful life for us. Sometimes, like having the flu on your birthday, we are unable to enjoy life to the full and the reason is sin.
Sin can be a dark cloud looming in the sky on an otherwise sunny day.
It's hard to enjoy life knowing that cloud is always out there. It's possible to still be happy when we're sick or in financial straits but it is not possible to be happy when we are in sin. The good news of Easter is that we never have to live under the shadow of sin. The only reason we live under that shadow is because we choose to. We are in the midst of the Easter season.
