The Westminster Shorter Catechism teaches us that “Man’s chief end is to glorify God and to enjoy Him forever.” It’s no mistake that the Westminster Divines, authors of this document, put this question and answer first in their catechism. They knew that it is of the utmost importance that we first glorify God. All that is good; all that is right; all that is eternally important flows from the recognition of God as God. We must notice that proper joy comes from glorifying God. There is eternal happiness wrapped up in that statement.
Another recognition missing from the formula of TWTH, is the fact of sin. That man is a sinner is a foundational fact of life. Because we sin we are incapable of keeping God’s law. In order to achieve the happier life promised by TWTH, every person on earth would need to keep each of its commandments. Though it can be in no way equated with God’s Moral Law, the formula of TWTH is still too hard. Sin bars the way. Only one way remains. Jesus is the way and the truth and the life. Without accessing the power of Christ’s atoning work on the cross of Calvary, one cannot achieve eternal happiness.
The Way To Happiness is simply another attempt to takeover; to hijack the truth of God’s Word. There have been many such attempts. They’ve been know by various names: theological liberalism, cultural liberalism, “New Age” religion, rationalism, pop psychology, psychiatry, “modern” science, the new hedonism (you know, the sexual revolution). Each of these is an attempt to make us feel better; to bolster our self-esteem; to reach our full potential – to find the way to happiness. This is Satan’s way to accomplish just the opposite. God’s Word teaches that without Jesus we can all feel better all the way to Hell.
