You do not keep God's commandment, because God never said to keep the law of the Sabbath in the new covenant, thus you are being unloving and creating a law unto yourself which is selfish and alters God's Word in your heart.

“Esteemeth every day alike. Let each man be fully assured” (Rom. 14.5). "Thou shalt not covet” a day of idolatry (Rom. 7.7). "Let no man therefore judge...a sabbath day: which are a shadow of the things to come; but the body is Christ’s” (Col. 2.16-17).

The demand of proof is on you to show otherwise.
