Excerpt from a prayer in The Valley of Vision:
Let me never forget that I have an eternal duty to love, honour, and obey thee [God], that thou art infinitely worthy of such; that if I fail to glorify thee I am guilty of infinite evil that merits infinite punishment, for sin is the violation of an infinite obligation.
John Frame says,
To glorify God is to reflect that light wherever we are, so that we image God more perfectly, so that people everywhere can see Jesus in us.
The Lord Jesus says,
Let your light shine before men, that they may see your good works, and glorify your Father in heaven.
The Apostle Paul says,
Therefore, whether you eat or drink, or whatever you do, do all to the glory of God.
Living for the glory of God, yes, it is that important; an infinite obligation.
