Before answering, one has to first establish the reason behind the Day of Worship question. If simply desiring to live according to God’s laws, the best advice is guiding the person scripturally. According to the Ten Commandments, the Seventh Day of the week is the Day of worship.
However, if desiring to be a Christian, the Day of Worship question would be irrelevant. Christians are not under the Law, as Christ would have taken over everything in their lives. Christians are a different creation, taking instructions directly from God, as guided by the Holy Spirit. To them, the Seventh Day Sabbath rest has become a day-to-day reality, rather than a once a week sign. See [The Seventh Day Sabbath is a sign of God’s Kingdom].
“The Law and the Prophets were until John; since then the good news of the kingdom of God is preached, and everyone forces his way into it. But it is easier for heaven and earth to pass away than for one dot of the Law to become void” (Luke 16:16) (ESV).
Before addressing the significance of this Scripture, let us first deal with the aspect of those forcing their way into God’s Kingdom. These are the people who assume that attaining salvation could be by other means, other than through Christ. These are the people who assume that the attainment of salvation is by works. See [Works bring the opposite of what is intended].
In Jesus we have the fulfilment of the Law and the Prophets. In other words, the reason why the day of worship is not relevant to true Christians, is that it was not relevant to Jesus. Nevertheless, when not yet decided to follow Christ, one can do well by just keeping the Law, according to the Ten Commandments. And that includes dedication to Sabbath-keeping.
“And behold, one came and said unto him, ‘Good Master, what good thing shall I do, that I may have eternal life?’ And he said unto him, ‘Why callest thou me good? There is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.’ He saith unto him, ‘Which?’ Jesus said, ‘Thou shalt do no murder thou shalt not commit adultery, thou shalt not bear false witness. Honour thy father and thy mother: and Thou shalt love thy neighbour as thyself.’ The young man saith unto him, ‘All these things have I kept from my youth up: what lack I yet?’ Jesus said unto him, ‘If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me’ But when the young man head that saying, he went away sorrowful: for he had great possessions. Then said Jesus unto his disciples, ‘Verily I say unto you, That a rich man shall hardly enter into the kingdom of heaven. And again I say unto you It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God’” (Matthew 19:16-24) (KJV).
This passage reveals that while Commandment-keeping can be virtuous, it is not sufficient for attaining eternal life. Eternal life requires surrendering everything considered as important. Apparently, as shown by addressing Jesus as “Good Master” the young man lived virtuously. This was commendable—in agreement with what ordinary people could see as goodness in Jesus.
But Commandment-keeping is not necessarily relevant to a true Christian; the term of which implies being Christ-like. The life of a true Christian implies being in communion with God, who dwells in that person’s life. People can be able to see the mind of God, in true Christians, who are a living testimony of what Godliness implies. When Jesus walked on earth, people could see God in the personality of Jesus.
But most people could not intimately relate with Jesus, though Jesus represented God in His life on earth. Humanity remains in the same state, as was projected in the lives of those in Jesus’ time. Only the disciples of Jesus could take seriously, the idea of intimately relating with Jesus.
The rest—like the young man describing Jesus as Good Master—loved Jesus. But those people could not maintain the necessary intimate relationship with Jesus. They could not go further than loving Jesus for what they could get out of Him.
