There is nothing wrong with keeping the Sabbath on a Saturday or a Sunday. If you keep the Sabbath because you enjoy it is no problem. BUT, if you keep the Sabbath on a Saturday because its demanded, then you are not doing the Will of the Father and its a sin.
Sabbaths, feasts, Holy days, we can keep if we want to but we do not have to because we are under Grace and not the Law.
Jesus came to fulfill the Law and to bring Grace to everybody.
We are no longer under the Law JFSurvivor, we are under Grace.
Did you know JFSurvivor there are 12 commandments?
Matthew 22:36-40
[SUP]
36 [/SUP] "Teacher, which
is the great commandment in the law?"
[SUP]
37 [/SUP] Jesus said to him, "
'You shall love the LORD your God with all your heart, with all your soul, and with all your mind.'
[SUP]
38 [/SUP] This is
the first and great commandment.
[SUP]
39 [/SUP] And
the second
is like it:
'You shall love your neighbor as yourself.'
[SUP]
40 [/SUP] On these two commandments hang all the Law and the Prophets."
Jesus added two other Commandments that are above the Ten Commandments.
We do not "keep" the Laws or the Commandments or feasts or Holy Days to receive Salvation.
