Surely it is good to go to church on Sunday and worship God!
It is good providing the motivation is good, and it serves the cause of Good if it makes you a better person; but all too often attending church is a matter of habit, or form and convenience, and the church ritual no more than an empty mouthing of prayers and praise. If attending church on Sunday makes you a better person during the rest of the week, then God is well served. If prayers and praise are seen not as supplications, but as means of attunement with The Supreme Spirit, then things are in their right perspective and God will not be indifferent to the sincerity of the effort. Worship must be approached, not with the mind of a mendicant but with a consciousness of the Divine Spark within seeking to attune with its source.
