Every day belongs to God. But Sunday is the Lord’s day in a special way. Jesus has owned it uniquely ever since that first Easter when He stepped out of the empty tomb. Think of it. On that morning, for the first time, He had conquered death. He had atoned for our sin. He had made a way for us to come boldly into the presence of the Father. And every Sunday since then has been an anniversary of that amazing morning. The Saviour has risen - and everything has changed.
