The Lord’s Day. On the 7th day, God rested from all His works. He declared it a holy day, that no man should work. Also in Israel, the 7th year was a year to let the earth rest from farming. When God made the sun and moon, He said the sun would rule the day and the moon night. The church in the 1st century, meet on Sunday to avoid conflicts with the Jews. We have kept it ever since. The bible also talks about the Day of the Lord. This is when Jesus will return to reign and rule on earth. It also refers to the judgement day. In 2 Corinthians, the bible says, now is th time, this is the day of salvation. This day is very important to God. Why, because gives us this day. He guarantees us now, this time, this day. This is the day the Lord has made and I will rejoice and glad in it. This day is the reality of Christianity.
