“So, whether you eat or drink, or whatever you do, do all to the glory of God. ” (1 Corinthians 10:31, ESV)
...and...
“But I say, walk by the Spirit, and you will not gratify the desires of the flesh. ” (Galatians 5:16, ESV)
...and...
“for you were bought with a price. So glorify God in your body. ” (1 Corinthians 6:20, ESV)
My point is that we should live our lives in such a way that all we do is "with/for" God. If we are doing anything that can not be done for His glory, we should repent and stop doing it.
I also agree with Pastor Eshelman, that in terms of time for explicitly worshipping God, God has ordained the Christian Sabbath for the "public and private exercises" of worship.
