The central message of this sermon is that humanity is designed to worship, and everything we do is a result of weighing reasons and choosing what we believe to be most important. This implies that our actions, including sinful ones, are driven by what we worship or hold as supreme importance. The sermon argues that God has created us with an inherent need for fellowship and worship, but sin has separated humanity from fulfilling this design, causing people to look elsewhere for meaning and significance. Ultimately, the sermon posits that those who do not worship God instead worship "created things" (idols) such as causes, ideas, or even themselves, leading to a life of rebellion against their true purpose and nature. The takeaway is that our choices and actions are driven by what we truly believe to be most important, and that this can either align with the ultimate importance and worth of God or with something else entirely.
