Yes, I did have Hebrews 10:25 in mind.

What does Hebrews 10:25 mean by "not forsaking the assembling of ourselves together"?

Does it mean that we should be found in church on the Sabbath?

Does it also mean that God frowns on us not being found in church on the Sabbath?

Corporate worship is what Christ himself designed for sharing our personal insights, to gain and offer views on truth.

Does the Bible and/or the writings of EGW have anything to say about this?

We sustain a loss when we neglect the privilege of associating together to strengthen and encourage one another in the service of God. The truths of His word lose their vividness and importance in our minds. Our hearts cease to be enlightened and aroused by their sanctifying influence, and we decline in spirituality. In our association as Christians we lose much by lack of sympathy with one another. He who shuts himself up to himself is not filling the position that God designed he should. The proper cultivation of the social elements in our nature brings us into sympathy with others and is a means of development and strength to us in the service of God. {SC 101.2}

If Christians would associate together, speaking to each other of the love of God and of the precious truths of redemption, their own hearts would be refreshed and they would refresh one another. We may be daily learning more of our heavenly Father, gaining a fresh experience of His grace; then we shall desire to speak of His love; and as we do this, our own hearts will be warmed and encouraged. If we thought and talked more of Jesus, and less of self, we should have far more of His presence. {SC 101.3}
