If God is not in your heart and soul then,your not going to find God in a church. Stand on a seashore, climb to the top of a mountain. Look out at all her has created and then tell me you don't see God. Sit there in slience and God will speak to you.
I think it's best to strive not out of guilt or obligation or some man made rule of when we should worship in churches...there is not a holy obligation that God is more pleased with us because we worship on such and such a day---again, the man-made religiosity of the church. All is sacred, all days are holy, and we can "keep the Sabbath holy' by cultivating this understanding, I believe.
