I guess 'Church at home' is a perspective issue. ALL children of God are called to minister the Word-You don't have to be a Pastor. You can simple pick some verses and discuss them with your family members-some would call this 'family devotions'.
We ARE the Church-the 'Body of Christ'. When you go to 'Church' it is just a building with the Church congregating inside. You can be a Church at home-as a matter of fact-we are called to be the Church everywhere we go-to be the example.
I have a feeling God is wanting you to step up and take the reigns of leadership spiritually in your family. Get Hymn book, a Bible and spend some time together worshiping and mediating on God.
'Where your treasure is-your heart will be also' Where is your heart?
