The Bible clearly tells us that Yahwey has set times and seasons and Yahwey spoke of signs. The hour is only known to Yahwey because Yahwey is the one who sets the sun, the stars and the moon in their motion and their order.
You must remember, Yahushua taught in what are call parables. He spoke to His own culture, His surroundings and by using what they knew and believed, the oracles of Elohim. He knew that the people knew that Yahwey is the One who alone knows the hour of when He will show the sliver of the moon.
Study the Feast of The Lord and you will see how His Son fulfilled the first three feast’s and we can only expect that since Yahushua Himself said that He did not come to abolish His law or His prophets so we can safely assume that He will fulfill the fall feasts as well.
The Feasts OF God are beautiful shadow pictures of Yahwey’s redemptive work through His Son. Even Paul said so.
Ask the Holy Spirit to teach you. You do not need that any man teach you. Proverbs 2: 1-5
