The main blessing of God's everlasting Covenanant is his free gift to those who believe - reconciliation with him. It's so important to remember our great need to be reconciled to him because our sins had separated us from him. We must also remember the means by which God's wrath against sin is appeased, his holy justice satisfied and our sins taken away - by the sacrifice Jesus made for us. Turn to Jesus and believe in his name.
“Remember the Sabbath day, to keep it holy. Six days you shall labor, and do all your work, but the seventh day is a sabbath to the LORD your God…For in six days the LORD made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy.”
