Humanism in "Christianity"

A little while ago I posted a few thoughts regarding how egocentric we are as people and the fact that most of us live with a Humanistic worldview. Basically, the chief end of man is the happiness of man. Without rehashing everything I said previously, I came across a paragraph in a book I am reading, "The Knowledge of the Holy" by A.W. Tozer, that fleshes out some of what I have been wrestling with. It is crazy, once you take a minute and really grasp this fact, you begin to realize just how much we really do have humanistic worldviews and view much of Christianity through this lens. Anyway, here is the quote:

"Too many missionary appeals are based upon the fancied frustration of Almighty God. An effective speaker can easily excite the pity in his hearers, not only for the heathen but for the God who has tried so hard and so long to save them and has failed for want of support (sarcasm). I fear that thousands of younger persons enter Christian service from no higher motive than to help deliver God from the embarrassing situation His love has gotten Him into and His limited abilities seem unable to get Him out of. Add to this a certain degree of commendable idealism and a fair amount of compassion for the underprivileged and you have the true drive behind much Christian activity today."

Jesus did not die on the cross hoping that some people would see what He did and choose to give Him permission to justify them. He died on the cross and effectually purchased and justified His church (Romans 8:28-30 ; Ephesians 5:25-33). He doesn't need our help to rescue the power of His blood from going to waste in the sinners life. No, His blood and resurrection accomplished the task it set out to do for His bride and He demands that His bride follow His commands, savor His Grace, pursue His Holiness and say to others - 'Behold the Lamb of God!' - and then beg God, in His sovereignty and by His Word, to break and transform the sinner.

The point of this is that evangelism and service to others is not about giving someone else hope for happiness either here in this life or in the life to come. If our compassion for others lies in simply seeing the "underprivileged" served and have their chance at a life of joy in Christ....than that is humanism. That says that the chief end of man is for mans joy/happiness -- either here or in the life to come. We should seek to serve and evangelize in a way that points to the Glory and Majesty of God through His Word so that it breaks the sinner and allow God to sovereignly transform a life that seeks His joy and Glory, not ours.
