The right motive in doing good works

I'm studying for a sermon from Titus 2:11-14. This passage unfolds the glory of the gospel and ends in saying that Jesus gave Himself for us to purify for Himself a people for His own possession, zealous for good works. Christians have the high calling of doing good works. That reminds me of Ephesians 2:10 which says that we are God's workmanship, created in Christ Jesus to do good works.

I gotta get back to studying, but I found this quote from Charles Spurgeon in a sermon he preached from Titus 2 entitled, "Good Works". He's dealing with the proper motive in doing good works and I found it very helpful, convicting, and purifying to my soul.

Again, nothing is a good work unless it is done with a good motive; and there is no motive which can be said to be good but the glory of God. He who performs good works with a view to save himself, does not do them from a good motive, because his motive is selfish. He who does them also to gain the esteem of his fellows and for the good of society, has a laudable motive, so far as man is concerned; but it is, after all, an inferior motive. What end had we in view? If for the benefit of our fellow creatures, then let our fellow-creatures pay us; but that has nought to do with God. Work is not good, unless a man does it with a view to God's glory, and he has been brought into subjection to God's divine will, so that in everything he has an eye to the Most High, and works in order to promote his glory and honor in the world.

And even, beloved, when our works are done from the best motives, nothing is a good work unless it is done with faith; for "without faith it is impossible to please God." Like Cain, we may build the altar, and lay the first fruits of the salt of faith, there it will lie-it will not be accepted by God, for without faith it is impossible to please him. Bring me a man who all his life long has been spending his health and strength for his fellow creatures; fetch me some public officer, who has fully discharged his trust, who has laboured night and day, even to the wearing down of his constitution, because he believed that England expected every man to do his duty, and he wished to do it; bring me that man; let me see all his charitable works; let me witness the most lavish benevolence, the most profuse bounty; tell me that he has always, with a consistent motive, laboured for his country; and then, if he cannot answer this question. "Dost thou believe in the Son of God?" I shall be bound in all honesty to tell him that he has not done a solitary good work in all his life, so far as God is concerned.
