What role does faith play in union with Christ?

In the context of union with Christ, faith acts as both evidence and result. While one must believe in Christ for there to be a real connection, the act of faith itself does not form the union—it is a manifestation of it. As highlighted in the sermon, faith is given by God and is a response to the work of the Holy Spirit in a believer's life (Ephesians 2:8-9). Thus, faith is the means through which believers actively acknowledge their relationship with Christ, showcasing their trust in His completed work of salvation. Therefore, true faith is intrinsic to experiencing and expressing this vital union.
