Read Matthew 12:1-30Bernie Girl.... Jesus was "working" on the Sabbath doing good.

As you see in Matthew 12, the Pharisees were more proud of their observance of tradition of the Sabbath that they blasphemed The Holy Spirit because of it and lost their salvation.
Lord of the Sabbath
1At that time Jesus went through the grainfields on the Sabbath. His disciples were hungry and began to pick some heads of grain and eat them. 2When the Pharisees saw this, they said to him, "Look! Your disciples are doing what is unlawful on the Sabbath."
3He answered, "Haven't you read what David did when he and his companions were hungry? 4He entered the house of God, and he and his companions ate the consecrated bread—which was not lawful for them to do, but only for the priests. 5Or haven't you read in the Law that on the Sabbath the priests in the temple desecrate the day and yet are innocent? 6I tell you that one greater than the temple is here. 7If you had known what these words mean, 'I desire mercy, not sacrifice,' you would not have condemned the innocent. 8For the Son of Man is Lord of the Sabbath."
9Going on from that place, he went into their synagogue, 10and a man with a shriveled hand was there. Looking for a reason to accuse Jesus, they asked him, "Is it lawful to heal on the Sabbath?"
11He said to them, "If any of you has a sheep and it falls into a pit on the Sabbath, will you not take hold of it and lift it out? 12How much more valuable is a man than a sheep! Therefore it is lawful to do good on the Sabbath."
13Then he said to the man, "Stretch out your hand." So he stretched it out and it was completely restored, just as sound as the other. 14But the Pharisees went out and plotted how they might kill Jesus.
God's Chosen Servant
15Aware of this, Jesus withdrew from that place. Many followed him, and he healed all their sick, 16warning them not to tell who he was. 17This was to fulfill what was spoken through the prophet Isaiah:
18"Here is my servant whom I have chosen,
the one I love, in whom I delight;
I will put my Spirit on him,
and he will proclaim justice to the nations.
19He will not quarrel or cry out;
no one will hear his voice in the streets.
20A bruised reed he will not break,
and a smoldering wick he will not snuff out,
till he leads justice to victory.
21In his name the nations will put their hope."
Jesus and Beelzebub
22Then they brought him a demon-possessed man who was blind and mute, and Jesus healed him, so that he could both talk and see. 23All the people were astonished and said, "Could this be the Son of David?"
24But when the Pharisees heard this, they said, "It is only by Beelzebub, the prince of demons, that this fellow drives out demons."
25Jesus knew their thoughts and said to them, "Every kingdom divided against itself will be ruined, and every city or household divided against itself will not stand. 26If Satan drives out Satan, he is divided against himself. How then can his kingdom stand? 27And if I drive out demons by Beelzebub, by whom do your people drive them out? So then, they will be your judges. 28But if I drive out demons by the Spirit of God, then the kingdom of God has come upon you.
29"Or again, how can anyone enter a strong man's house and carry off his possessions unless he first ties up the strong man? Then he can rob his house.
30"He who is not with me is against me, and he who does not gather with me scatters. 31And so I tell you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven. 32Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.

Also Romans 14:5 is addressing the fact that the Hebrew calendar was a lunar calendar and revolved around the cycles of the moon -- from first moon to full moon, and the Roman calendar was a solar calendar and revolved around the cycles of the sun; so, therefore, the Sabbath day or Seventh Day would fall on different days due to two different calendars, as a lunar calendar has more days than a solar calendar.
Also, Romans 14:5 addresses that any day is worthy of worship and rest in The Lord, including all days. As it says "one man considers one day more sacred than another; another man considers every day alike.
So, all days of worship and/or rest are welcomed by The Lord. In my mind, every day belongs to The Lord.
We do, however, need rest. Rest in him.
However, if you feel you are doing good on The Sabbath... you shouldn't condeem yourself. The scriptures don't.
