"Remember the sabbath day, to keep it holy.
Six days thou shalt labor, and do all thy work:
But the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day and hallowed it." -Exodus 20:8-11
"And let us consider one another to provoke unto love and to good works:
Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as you see the day approaching." -Hebrews 10:24-25
"Iron sharpeneth iron; so a man sharpeneth the countenance of his friend."
Going to church will not get us into Heaven, but it does bring God glory, keeps us accountable and on a righteous path.
