Yes, EVERY Lords day should be used to celebrate Christs resurrection ect, but not every Sunday is specifically focused on that is it?
Joshua, if a church proclaims the gospel faithfully then the resurrection is emphasized each and every Lord's Day. All preaching should be Christ-centered preaching. All Christ-centered preaching is rooted in the hope of the resurrection. It doesn't matter whether the topic of the sermon is resurrection related or not; the very fact that Christians gather on the Lord's Day is because of the resurrection.
