What would you say are the messages He would preach today? Certainly there are more than one, and I notice you are strong on keeping the Sabbath. What is it He and His servants would (and thus should) be preaching today to bring forth the fruit of righteousness from His vineyard?
The same message that Christ brought during His first Advent. Christ came with the message of the Salvation Covenant, that was offered to Cain: -
Genesis 4:6-7: - 6 So the Lord said to Cain, "Why are you angry? And why has your countenance fallen? 7 If you do well, will you not be accepted? And if you do not do well, sin lies at the door. And its desire is for you, but you should rule over it."
Christ also pointed to this same Salvation Covenant when He said: -
Matthew 13:52: - 52 Then He said to them, "Therefore every scribe instructed concerning the kingdom of heaven is like a householder who brings out of his treasure things that have been refreshed and yet still old from the time of Adam and Eve."
God gave the following insight for Israel to act on: -
Daniel 9:24: -
24 "Seventy weeks are determined
For your people and for your holy city,
To finish the transgression,
To make an end of sins,
{After which, I will make the following to happen: -}
To make reconciliation for iniquity,
To bring in everlasting righteousness,
To seal up vision and prophecy,
And to anoint the Most Holy.
What was the sin that Israel had to end?
It was the sin of idolatrous worship.
What was the consequence of not repenting of, and finishing with, their sin of Idolatry?
Then The second Commandment of the Ten would kick into play: -
Exodus 20:4-6: - 4 "You shall not make for yourself a carved image — any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; 5 you shall not bow down to them nor serve them. For I, the Lord your God, am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth generations of those who hate Me, 6 but showing mercy to thousands, to those who love Me and keep My commandments.
which is also expanded upon in Leviticus 26 and Deuteronomy 8 where it describes what will happen to them if they do not follow God's ordinances for the Nation of Israel which also contains the Blessings that will if, while the visitation of their iniquities upon them, they repent.
Jeremiah speaks of the time that Israel will come to seek the Lord and the events that will occur around this same time.
Isaiah 58 also speaks of the fasting that God desires of Israel leading up to the time of the Sabbath Day/Age for all of mankind. During this time God will put a stop to the influence of the wicked heavenly hosts by locking them up for an extended time during this age, before they are released for a little while period to do their worst as if this is God's means of separating the Flock from the flock before He then separates the Sheep from the Goats.
We are also told by Christ, that Satan will also, during the Sabbath Day/Age, also have empowered his good and faithful servants to continue his oppression of the people of the earth such that they become distracted from the things of God during this age, before he returns for his last final fling.
How de we keep this Sabbath Day/Age of the Lord Holy?
For those that enter into the Last Age, by choosing to enter into a lasting relationship with God, on His Terms, during the time that His Everlasting Kingdom will be present on the earth. This Everlasting Kingdom will be establish at the time of Great upheaval and turmoil on the earth in our near future.
The same is also true for those who have come during the ages before the final age, to enter into a lasting relationship with God on His terms and conditions.
The choice to keep God's Sabbath Day/Age for mankind Holy is our choice during the next Age.
We do it by the circumcising of the flesh around our heart and choosing to worship only God, the Father.
Shalom

that have been coloured thus.
