So between the death of Christ and the Last Day it is only by a gracious anticipation of the last things that Christians are privileged to live in visible fellowship with other Christians. It is by the grace of God that a congregation is permitted to gather visibly in this world to share God’s Word and sacrament. Not all Christians receive this blessing. The imprisoned, the sick, the scattered lonely, the proclaimers of the Gospel in heathen lands stand alone.
