In Hebrew, Shabbat means rest. The Sabbath is the seventh day of the week. In our Gregorian system, that day generally falls on Saturday. It is to be a day purposely set aside to slow down our pace and shift from the regular work routine (Exodus 20:9-10), a time for refreshing (Psalm 23), and a time to focus on God and family. It is for the benefit of believers (Mark 2:27, Hebrews 4:9-10) and not burdensome. Come to Me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from Me, for I Am gentle and humble in heart, and you will find rest for your souls. For My yoke is easy and my burden is light. ~Matthew 11:28-30
Any day can be a time for fellowship and worship with other believers, but the Sabbath can certainly be a time for it. I will not get into the Saturday versus Sunday debate nor the issue of what constitutes work and what does not. That is between you and the Lord. However, I would encourage you to study and pray over the subject of traditions of men (human traditions) versus God's traditions and to walk in the Way in which Yeshua walked. The more we become like Him, the more we will be blessed. The main point is truly that only Yeshua gives true rest.
If you turn away your foot from the Sabbath, From doing your pleasure on My holy day, And call the Sabbath a delight, The holy day of the Lord honorable, And shall honor Him, not doing your own ways, nor finding your own pleasure, not speaking your own words, Then you shall delight yourself in the Lord; and I will cause you to ride on the high hills of the earth, And feed you with the heritage of Jacob your father. The mouth of the Lord has spoken. ~Isaiah 58:13-14
One person esteems one day above another; another esteems every day alike. Let each be fully convinced in his own mind. He who observes a day, observes it to the Lord; and he who does not observe the day, to the Lord he does not observe it......So then each of us shall give account of himself to God. Therefore let us not judge one another anymore, but rather resolve this, not to put a stumbling block or a cause to fall in our brother's way. ~Romans 14:5-6, 12-13
God watered the ground with a mist and a system of rivers and planted a beautifully complete garden with many animals. He then created man from dirt, named him Dirt/Adam for humility and placed him in the garden to tend the garden and the animals. He has shown you, O man, what is good; And what does the Lord require of you but to do justly, to love mercy, and to walk humbly with Yahweh? ~Micah 6:8
In the midst of the garden were two trees, the tree of life and the tree of the knowledge of good and evil. All of the vegetation in the garden were given for food except for the tree of the knowledge of good and evil which was forbidden because partaking of it would lead to death. There is a way that seems right to a man, but its end is the way of death. ~Proverbs 14:12
Pay attention, that at this point God only gives one negative command and it boils down to God's Way versus man's way. Every way of a man is right in his own eyes, but the Lord weighs the hearts. To do righteousness and justice (obedience as He defines it) is more acceptable to the Lord than sacrifice. ~Proverbs 21:2-3
Then God determines that the man was lonely and needed a mate. He made the woman from one of Adam's ribs and declared them husband and wife, the first marriage covenant. He who finds a wife finds a good thing, and obtains favor from the Lord. ~Proverbs 18:22 Two are better than one, because they have a good return for their labor: If either of them falls down, one can help the other up. But pity anyone who falls and has no one to help them up. Also, if two lie down together, they will keep warm. But how can one keep warm alone? ~Ecclesiastes 4:9
Remember to ask the Holy Spirit to show you truth in the scriptures and how to apply it to your life.
