In this sermon from Romans 1:21–23, we reflect on the condition of the human heart apart from the grace of God. Paul shows how humanity, though knowing about God through His revelation, refused to honor Him or give thanks. The result was spiritual darkness, futile thinking, and idolatry. Yet this passage also humbles us, reminding us that apart from God’s grace, their heart is our heart. Join us as we consider the seriousness of sin, the danger of rejecting God’s truth, and our desperate need for the mercy and saving grace found in Jesus Christ.
