God bless you brother, let's look at the Bible.
Deut 5:12 Keep the sabbath day to sanctify it, as the LORD thy God hath commanded thee.
Deut 5:15 And remember that thou wast a servant in the land of Egypt, and that the LORD thy God brought thee out thence through a mighty hand and by a stretched out arm: therefore the LORD thy God commanded thee to keep the sabbath day.
The word "therefore" Deut 5:15 says I should keep the Sabbath only if I or my ancestors were slaves in Egypt. Sabbath has nothing to do with Gentile Christians and it never has.
So you are saying that not keeping the Sabbath is not for the Christian. Why was Jesus concerned about His Sabbath when He prophesied of the destruction of Jerusalem?
"And pray ye, that your flight be neither in the winter, NOR ON THE SABBATH DAY"- matthew 24:20
And what does Luke 16:17 mean to you?
How about Rev 22:14? Rev 14:12? 1 john 3:8 and 1 john 3:4? What about our lovely 1 john 5:3? 1 john 2:4?
Salvation is by faith. But your faith is dead if you wilfully continue in sin.
Romans 6:15 and romans 3:31 has become my favorite verse almost because no one can answer it. You claim because you got faith, you are released from obligation to the law:
"Do we then make the law void through faith? God forbid. We establish it."- romans 3:31. Paul is saying a big NO to the assumption "you are released from obligation to God's Law". he rather says, God forbid, we will establish the law.
Here's a striking statement too: "shall we sin because we are not under the law, but under grace? GOD FORBID."- romans 6:15.
EXODUS 20:1-17.
Revelation 22:14, "blessed are they that do His commandments, that they may have right unto the tree of life, and may enter in through the gates into the city."
I hope you have understood. It's a lie to keep you out of the holy city, New Jerusalem, that you can go ahead and break carelessly God's law. If you do sin, even though you were honest, you have an advocate with the Father, Jesus Christ the righteous. But you don't wilfully sin and spray gravel over God's mercy.
