How do we know Christ's presence is with us during communion?

The presence of Christ in communion is not physical but spiritual, emphasizing our faith in Him as we partake of the symbols of bread and wine. As stated in the sermon, these elements serve as a memorial of Christ's sacrifice, reflecting on His body and blood but are not to be misconstrued as literally becoming His body and blood. The act of communion is an opportunity to affirm our relationship with Christ, reminding us that He is our righteousness and that our worthiness comes from our recognition of our need for Him.
