In Part 4 of our Marks of a Healthy Church series, Biblical Conversion, we explore what it truly means to be changed by God. Conversion is more than adopting a new set of beliefs or making an effort to become a better person—it is a supernatural transformation of the heart and nature through God's grace. Scripture reveals our need for this change, God's initiative in bringing it about, and our response through repentance, faith, and surrender to Jesus Christ as Lord. Through passages including Romans 3, John 6, and Ephesians 2, we discover that genuine conversion is not simply something we do, but something God does within us, making us new through the power of His Spirit. The message challenges us to consider a deeply personal question: Does the Spirit of God truly dwell in you?
