A study about Yahweh's time is difficult. Any thought that the time we currently use may be wrong or Satanic seems instantly ridiculous. The only "time" we have ever known is Satan's false time. We have grown up with it and it seems natural and correct. Instead, it is only familiar, but it is artificial and wrong.
But, why should we even contemplate the subject?
1 Corinthians 2:14
But the natural man receiveth not the things of the Spirit of יהוה [Yahweh, our god]: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
John 1:2-5
All things were made by him; and without him was not any thing made that was made. In him was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.
It is only through the Spirit that you may be urged to study deeper into this subject. It needs study because (1) Yahweh's time is related to harvests, which typify our salvation and (2) observing Yahweh's time is the only way we can keep our appointments with our Maker and find His Sabbath day.
Some differences are subtle, others will seem impossible to grasp. The first difference one sees is the naming of days and months after pagan gods. I object to that, but have no problem saying "Monday" (named after the moon god) because I know there is no such thing. There are Bible verses that recommend abstaining from meat offered to idols (Acts 15:20, Acts 21:25). But Paul tells us that false gods don't exist, there is only one God (Elohim). So eating meat offered to idols is nothing.
1 Corinthians 8:1-6
Now as touching things offered unto idols, we know that we all have knowledge. Knowledge puffeth up, but charity edifieth. And if any man think that he knoweth any thing, he knoweth nothing yet as he ought to know. But if any man love יהוה [Yahweh], the same is known of him. As concerning therefore the eating of those things that are offered in sacrifice unto idols, we know that an idol is nothing in the world, and that there is none other Elohim but one. For though there be that are called gods, whether in heaven or in earth, (as there be gods many, and lords many,) But to us there is but one Elohim, the Father, of whom are all things, and we in him; and one master, Yahushua the Messiah, by whom are all things, and we by him.
Likewise saying the words "Monday" or "January". There is no moon god nor any god called Janus, so saying their (non-existent) names mean nothing to me. Paul does, however, recommend against harming a brother whose conscience is pricked by this (1 Corinthians 8:9-11). Oh, if only it were so! It would be wonderful if many consciences were pricked by hearing or saying the names of these pagan false "deities". Instead, the whole world "wonders after the beast" and uses its names of these pagan gods, daily. How sad that hardly anyone notices or considers anything amiss.
It's easy finding / knowing Satan's time. Everyone uses it. It's on everyone's computer and cell phone. Its on every calendar on a wall.
Finding Yahweh's time is a little difficult at first. Every shepherd and men with no learning at the time of Christ knew. But we don't. Those living in asphalt jungles are far from Yahweh's nature. The purpose of this study is to (re-)introduce you to nature and Yahweh's time.
