There is not such thing that when you die you will become an angel and will be watching down from heaven. As matter of fact the Bible says that each person is destined to die once and after that comes judgment! (Hebrews 9:27) Heaven is only destined as Jesus stated for those who are born again! (See John 3:3) This means only those who have been forgiven from their sins and follow Jesus Christ as their Lord and Savior, walking in love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control! (See John 3:16 + Galatians 5:22-23)
But those who follow the desires of their sinful nature produces these evil results in their lives: sexual immorality, impure thoughts, eagerness for lustful pleasure, idolatry, participation in demonic activities, hostility, quarreling, jealousy, outbursts of anger, selfish ambition, divisions, the feeling that everyone is wrong except those in your own little group, envy, drunkenness, wild parties, and other kinds of sin. Anyone living this sort of lifestyle will NOT inherit the Kingdom of God!!! (See Galatians 5:19-21)
There is no law in the New Testament or command or rule given to the Church to keep the Sabbath, or even Sunday as the rightful church day. Sunday is not a day that replaced the Sabbath, or the only day we are required to assemble and worship. The Bible makes it indisputably clear that we are absolutely not required to keep the Sabbath, festivities, or any other day. Here it is:

God’s desire is that we worship and serve Him continually, every day, not just on Saturday or Sunday. That is why there is no explicit biblical command that either Saturday or Sunday must be the day of worship! That’s why the scriptures also say;
“In the same way, some think one day is more holy than another day, while others think [...]
