Living for God's Glory

Do we really believe Romans 8:28?
And we know that for those who love God all things work together for good, for those who are called according to his purpose.

We must live for his glory and fight the fight of faith to be holy.
Consider the following quote form John Calvin:

I call "piety" that reverence joined with love of God which the knowledge of his benefits induces. For until men recognize that they owe everything to God, that they are nourished by his fatherly care, that he is the Author of there every good, that they should seek nothing beyond him -- they will never yield him willing service. Nay, unless they establish their complete happiness in him, they will never give themselves truly and sincerely to him.

It's our sinful nature that tells us that "we" are the only one who knows how to run our own life. A lie from the prince of darkness himself. God knows ALL. Remember "I AM WHO I AM"? When God said that He already knew ALL about His children in Egypt and He also knew how it would end as well.

So who would you rather live for? Yourself, who has a proven track record of failure?
Or, would you rather live to the Glory of the God of the universe and let him help direct your paths?
