Son, you should never start using a tool you have not tested; drinking of water when you know not it's source; or partake of meats not knowing of the hand that prepared it.

The Lord has given us His Word, which is our well tested tool, for living in honour and truth; drink the water given by the Spirit, and it will teach you of the true ways; and eat of the gospel food from God's living Word through the Spirit of grace.
 

The expression of TIMING is found in this context as referring to Gal. 3:28-29 – “There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus, And if ye be Christ’s, are ye Abraham’s seed, and heirs according to the promise.” So this lesson goes back to Gen. 1:1 – The initial Creation of all things even making the first human - Gen. 2:7, so we then go forward through the seed of Abraham, including his son Isaac, then Abraham's grandson Jacob, who started the 12 Tribes as found in Gen. 49:1-33, including the period of total destruction of all humanity which also included some of God's sons in the days of Noah’s Flood, at which time only 8 human-beings remained alive, (Noah and his family) Gen. 6-

chapter 10:1. So here is the family history of the generations of humanity which died, before the 12 Tribes of Jacob – Gen. 49. Even though Moses later wrote the first 5 books in the Bible, he was not yet born, but was of the 12 tribes. This period of about 3900 years included a multitude of people both of the elect and non-elect. The many elect family members of God’s people, who had then so lived and died, had their names recorded in the Everlasting Covenant written before Gen. 1:1. So, John factually granted and testified that all of God’s elect family in Rev. 5:9 to have been chosen OUT OF EVERY kindred, tongue, people and nation.
