Being holy at church means smiling politely at the person who irritates you. It means singing with gusto during the group singing time. It means listening carefully to the speaker even when you are not that interested. But being holy at home...well that's another thing entirely... or is it? Maybe we are trying too hard to bring specific activities under the guise of holiness. Maybe there is more to holiness than superficial smiles and strong-sung songs. I think if we asked Jesus He would tell us that holiness is more a matter of the heart. That is best understood by the simple word "Love". Holiness at home and holiness at church is the same as holiness anywhere. It is acting in a spirit of love.
James 2:8 "If you really keep the royal law found in Scripture, "Love your neighbour as yourself," you are doing right."
Being holy is hardest at home...unless you remember...being holy is simply being loving.
In that case, how hard it is to be holy at home depends on how hard or easy you find it to behave lovingly toward those in your home.
